NASATV. There are many interesting shows by the hour on NASAA TV. aeach sghow last 1/2 hour and is packed with interesting info about Astronomy. Reaswons why AWebbh Telescope was delayed from orignal launch dat eo f2007 until Dec 2021? Complexity of building the telescope and over optimisti8c projections. The mirros, for example, operate at cold temps, close to aboslute zero, in wspace. But they are tested at romm temperature on ASEarth. AWhen the mirros are unfolded in space, they will warp differently than they do on AEarth, so fitting them together is crucial. Also, on a typical NASA launch are are 5 to 10 failure opoints. If any oif these 10 go wrong, the mission is mostl likely scrubbed. On the AWsebb launch, there were 344 fgilure points. Much more comp[licate, risky abnd dangerous. ISS research on flames and fire. Flames burn differently in space anbd micro-G. Learning about this can make engines burn efficiently on Aearth. Building protections in power grids on Aearth, against solar storms. SAcienties are studying a very dangerous solar storm 9,200 years ago and during the Carrington AEvenmt in SApet 1859. It any of these 2 storms hit now, AEarth's power grids would not be protected. There could be ctostrophic damage. It is dangerous when solar storms smah into AEarth's atmosphere at the wrong part of the solar cycle. Need to build in better protections. The SLS SApace Launch SAystem of rocket s are being tested for a treturn to the moon, and possible Mars. THE SLSA Mego Moon Roacke twas rollde out in June on a dress rehearsal.

Is global warming responsible for our cool spring? Major planetary alignmnent on the way. All planets, will be aligned, in order, in the night sky. WAill next happen in 186 years. The Chginese are threatening to shoot down aelon Musk's satellites because he believes they are spyting on Chinese interests. VChina has a telescope, FAST, the world's bigfest radio telescope. 500 meters across. FAAST picks up anaomolouys signals. Are they alien signals? Might just be radio interference. Also picking up Fast Periodic Bu8rsts, ir fast radio bursts, FRBs. Carry more energy in 1 milliseconde than the sun emits in 11 year. FRBs come and go quickly . 2020 first FRB found in the Milky AWay. Came from a magnetar, ahighly magnetized neutron star. 3 B LYs away. goes in different cyklces. 90 days of powerful radio bursts,m then 57 days of mild radio bursts. Then 157 flares across 47 days. Video of AWebb and its insturment suite. A micro-meteor impact occurred on one of AWebb's mirros on May 23 - 25. Did damage that cannot be fixed./ AWe4bb is going to open views of the most distant galaxies, but it will also allow scientists to see in m ore clarity inside our own solar stystem. Things like planets, asteroids and the Puiper Belt. More excitment in sotre with AWebb.

`A Wolf Moon in January. New Research suggests an early kick just after the Big Bangt created Dark Matter. Dark Matter Discussion.

Planck Length. Zepo-second. Review of the significanace of this data. 77% of Stars in MW are Red Dwarf Stars. Astros are trying to find Earth-like planets around Red Dwarfs. But some rocky exo-planets are close to their Red Dwarf stars. A Giant Black Hole Keeps Avoiding Detection. A big galaxy at the core of cluster Abell 2261, 2.7 billion light-years from Earth, should have an even larger central black hole — a light-gobbling monster that weighs as much as 3 billion to 100 billion suns, astronomers estimate from the galaxy's mass. But the exotic object has evaded detection so far. Largest canyon in Solar System revealed on Mars. Look on Hi-Rise website Nine epic astronomy discoveries you may have missed in 2020. Fermi Bubbles discovered in the X-Ray bublbles.

By studying exo-planet formation, this adds to the knowledge base of how planets form, and how they can move. Jupiter moved in its orbit a lot in the early solar system, and this had a profound effect on how our solar system and its planets formed. Super planet or brown dwarf? New theories are coming out about brown dwarfs. A brown dwarf, or planet, BDR J1750+3802, or Elegast, has been discovered by a radio telescope. The BD was not visioned previously. Solar power stations in space could be the answer to our energy/power needs on Earth. A new radio telescope in space is envisioned. This could also be placed on the moon. Millions of signals are detected in space from intelligent civilizations: the problem is, the intelligent civilization is us. Very few anamolous signals from supposed aliens have been detected. The search for extra-terrestrial signals are for techno-signatures. Some of these signals have been received by the Aricebo telescope, but, unfortunately, in the next week, the Aricebo telescope di4ed a slow but certain death.

The European Space Agency's Sentinel 5 Michael Frelick weather/climate satellite was launched Nov 23. It will track seal level rise, which is due to global warming. Fast Radio bursts FRBs have been tracked from the Milky Way, for the first time. (30.00 light years away) SGR 1935+2154 provides the first evidence for the origins of FRBs. Scientists have some ideas about other objects tat might create FRBs, but they are not 100% sure. 12 strangest galaxies in the uiniverse. Contact has been re-established with Voyager II. With repairs ot DSS 43 in Canberra Australia, part of the Deep Space Network, contact was not possible for about 3 months because of repairs to DSS 43. An asteroid, 101429, is an trojan asteroid thought to have possibly come from the moon.

Entropy, order, disorder, and its meaning for life in the universe, and the eventual fate of the universe. When the universe first came into existence atoms, and light, did not exist. Galaxies come in different sizes, but also different shapes. The shape of a galaxy gives us a break down of the events in that galaxy's ultra-long life. There are 2 basic designations of a galaxy's shape, a disk, and an elliptical. Both the Milky Way and Andromeda are disks, formed from clouds of hydrogen gas. Ellipticals appear to be older and the movement of their stars appear to be more random. They are also thought to have formed from a galaxy merger. Galaxy mergers are thought to take millions or billions of years. The mergers that form irregular galaxies merging are thought to look like a big train wreck. There are also lenticular shaped galaxies. Elon Musk is testing his rockets to go to Mars. The window to go to Mars is every 26 months. Musk will launch on vehicle to Mars in 2024. Musk only plans to ferry humans and cargo to Mars. He does not want to build a settlement on Mars. A sepo-second is the shortest unit of time ever measured. A particle of light, a photon, produces waves. By measuring how long it takes for the waves of a photon to cross a hydorgen atom, a sepo-second can be measure. A zepo-second is 1.o x 10-20 of a second. Eleven fascinating facts about the Milky Way, Dirty grease, or aliphatic carbon compounds are interspersed thought out the Milky Way. The study of Fermi Bubbles, gamma ray emissions, and x-ray emissions, can tell about previous mergers of galaxies into the Milky Way. The Mily Way is also being bombarder by FRBs, Fast Radio Bursts, from other parts of the universe.

Apparently, Jupiter moved from its present orbit in the early solar system, and had a role in sculpting out and influencing how the inner planets developed. Proton gradients and their roles in the development, or sparking of life, on Earth. Entropy is always increasing in the universe. Life forms, like us, have low entropy, and are very ordered systems. Non living things have very high entropy, but all things in the universe are tending toward a state of higher entropy. Life takes energy and does useful things with it. three people were awarded for Black Hole work. Roger Penrose received half the prize for the discovery that black hole formation is a robust prediction of the general theory of relativity" and the other half jointly to Reinhard Genzel and Andrea Ghez "for the discovery of a black hole at the center of the Milky Way. Improving the exactness of the expansion rate of our universe will apparently help astros discover what dark matter is. Nuclear Fusion reactor could be here by 2025.

NASA has begun to choose equipment for the Gateway Station. This station will be a fixture, orbiting the Moon. Astronauts can deploy to and from Gateway to the Moon. These first sets of instruments selected for Gateway will observe space weather and monitor the Sun’s radiation environment. Other instruments will be choosen within the next few years. The Canadian Space Agency, ESA, and JAXA will also take part. One of the most important funcntions of Gatelway is prepare and rehearse for flights to Mars.

Biggest explosion in universe, and,,,,,,,,, they saw a cavity being blown out, maybe not the explosion itself.

Black Holes. What are they and how are they formed? We will distinguish between black holes that are produced by core-collapse supernova, and black holes that exist at centers of galaxies. Our sun will not turn into a supernova at the end of its life-cycle, but will instead become a carbon white dwarf. The life stages and fates of stars of different sizes will be discussed, as well as the processes involved when and after big stars go supernova. Guess what? Well also talk about aspects of relatively associated with black holes, and things like event horizons and space-time.

Watching Astronauts train: Fun!!! Bigest exkplosion in history from Ophiuchus galaxy cluster about 390 million light-years from Earth. Galaxy clusters are the largest structures in the universe held together by gravity, containing thousands of individual galaxies, dark matter, and hot gas. The explosion blew out a hole in the wall of the cluster. This explosion was 5 x bigger than the previous record holder. The biggest explosion of course, was the Big Bang. The previous record holder, MS 0735+74, and hundreds and thousands of times greater than typical clusters.

Jupiter Migrated In and Out in the early solar system, and carved out the solar system. Discussion about the early universe. When U turned 380,000 years old, U started to change. Discussion about LiveScience website. More exciting stories than NASA.gov.

An examination of space time from an article in Livescience.com. What Is Space-Time? By Adam Mann - Live Science Contributor . this article deals with the theories behind space time, and more specifically, the fabric of space time. Einstein combined space and time into 4 dimensions. This article deals with how space-time works, and what scientists still don't know.

Space Time, White Holes and Worm Holes.

A new satellite (spacecraft?) will be deployed to clear the space junk from outer space. About time. The universe remembers gravitational waves. Evidence of an intermediate sized particle called X17. Does X17 contain a fiftth force that could help explain dark matter?

UFO Reports Now Available in Canada. The Universe remembers gravitational waves. G waves warp space time and leave their imprint. When G waves wash over you, they leave their imprint. This echo can be measured, or so scientists think. But gravity is a weak force so its hard to measure so multiple events of g waves must be combined in order to measure them. 2,000 combined waves are needed. A few scientists believe a new particle, X 17, will reveal a 5th force of nature. Scientists hope this particle can help define what dark matter is. Space is littered with space garbage. ESA is proposing a robot that will hug garbage in space, and then clear the garbage out. The 4 armed robot will drag itself and the garbage to be burned up in the Earth's atmosphere.

Parker has many new finds about the mysteries of the corona. Parker is doing many flybys between Venus and the Sun, and has already challenged some of the current theories of the Sun. The probe will run until 2025. The first details about the Sun are HOOOOOOT. The probe is 23 million miles from the Sun to measure the solar wind and the corona. Our previous views of the sun were simple. Parker has found cosmic dust stops at a distance of 3.5 million miles from the sun. Parker also saw magnetic waves from the sun flip in a whip like motion 180 degrees in a matter of seconds. These switchbacks came in clusters. The solar wind now is known to have rough irregular texture. The plasma lacks an orderly sense of direction. Some flies out but some falls back. Parker also found a transition point in the solar wind. The corona rotates with the visible surface before it transitions and Parker spotted signs of the transition, and it now is known that it happens farther out than expected. Parker also observed several outbursts of solar energetic particles. They have never seen to be this small before. Amazing photos of the terrain of the moon.

The Parker Solar Probe has given a bonanza of new info about our star. Launched August 2018. It is targetting the solar wind and the solar corona. New lovely moon photos from LRO.

ACFER 094 crashed in the Sahara desert in the 1990s. Voyager !! went through a violent battle between the solar wind and cosmic rays from interstellar space. Voyager ! couldn't measure through this area because of a senfor malfunction. V II went through the heliopause, the edge of our solar system. The helippause protects us from interstellar space. Temperatures in the heliopause reached temperatures of 31,000 degrees Celcius, double what scientists previously predicted. This suggests a far more violent clash between the solar wind and interstellar space. The heliopauses' thick walls protect us from interstellar space. There were also 2 holes in our side of the heliopause. The 18 biggest unsolved mysteries in Physics. Bubbles of cooler universe cooled in the beginning after the Big Bang. V883 Orionis

The solar wind sends out a solar bubble all the way to the -, our cosmic border which protects us from the dangerous things in interstellar space. Quasi particles messing up my mind. Blah, blah, blah. 3 Black Holes cooking their galaxies alive. Cool (or hot?) How does this gas stay so hot??????

Different freaky stars are examined. BPM a white dwarf weighed 5 million trillion pounds and was the equivalent of 10 billion trillion trillion karats. 85% of the stars in the Milky Way system are 2 or higher order star systems. Where do Black Holes lead? The Oldest Known Black Hole.

Mercury recently transitted the Sun. Hubble photoed how light escaped from the earliest galaxes, turning the universe transparent. Top 10 star mysteries of all time. Star Quakes give strong magnetic wavesl. Super Stars. Rotating Radio Transers give off powerful magnetic fields. How light escaped from the earlies galaxies, and how this made the universe transparent.

50 Anniv launch of NASA rockets. Rainforests are burning and NASA is helping monitor this. Voayger II deliniates the boundaries of interstellar space. It is unknown how far out Voyayger II is from the heliopause. The plasma outside of the heliopause is considerably denser than astronauts believed.

Interstellar Medium Intergalactic Medium. Winds are transporting gases between these mediums. Oxygen Ions are emitting gas in galaxies. GCM --> seeing for the first time how the CGM is being mixed. This is called cosmic goo, the stuff in between galaxies. Top 15 Weirdest Galaxies in our Universe. How NASA might bring home pieces of Mars in a Darth Vader. Colliding Galaxies form piercing eyes of ghost face.

NASA and Google partner up. Quantum computers are demystifying the future of computing. A quantum is a the minimum of any physical thing that is needed to interact with something else. In QM, particles radiate in quantums. Computer scientists try to harness the properties of quantum mechanics in computing. Hopefully, computer can be done much faster. The event horizon telescope, which is the link up of 8 telescopes around the world, is trying to take a picture of a black hole. Trojan Asteroids.

Computers and Viewing Black Holes and the Intracacies. Why is the MW getting so gassy? Star clusters are born together. The first planet orbiting a sun like star outside our solar system. Scientists believe we will not be able to get to other stars, and especially we will not be able to habitate them. Going to Mars or another planet? Is it possible. Steven Kane says we might be able to send people to Mars in the next 50 years. To Jupiter? Noooooooo. To other stars? Noooooooooooooooooooooooooo. How the universe stopped making sense.

The Nobel was split between cosmology research to a Canadian and exoplanet research. The science community was upset about how the Nobel was awarded. Exoplanet research. Marcy and Butler research was finally awarded. A jet or trail of gas is arriving in our direction from the Magellanic Clouds. A large empty void is forming in space, far, far away, in Eridanus. Largest exoplanet, GQ LUPI B, has a radius 3.5 times that of Jupiter. UI SCUTI with a radius of 1,700 times that of the Sun. Largest Nebula Tarantula 1,800 LYs. or galaxy, IC 1101 weighing 200,000 more than the Milky Way. TON 618 Supermassive black hole, 66,000,000,000 Suns. Largest Fermi Bubble is 25,000 LYs tall. A large structure, a galactic cluster, is SPT 2349-56 weighing 10 trillion times the mass of the sun.

The Deep Space Network. Fast Moving Stars. Why? How to photograph a black hole? Creating complicated computer algorthrims is necessary. The Cannibal next store. Andrormeda is going to cannibalize the Milky Way one day. Planet 9 and TNOs, trans Neptunian objects, orbit in a different plane than the other planets. This suggests that something else, Planet 9, is tugging on them. Where can we find primordial, or grapefruit-sized, black holes.

OSIRIS-REx has narrowed down its list to 4 potential sample sites at the asteroid Bennu. Scenarios NASA has to plan for on a mission like OSIRIS-REx. 30 year anniversary of Voyager 2's visit to the planet Neptune.

No one know if astronauts would return from the Moon with contaminants, so Neil Armstrong was quarantined for 3 weeks after returning from the Moon. Titanium was found in higher proportion in moon rocks than on Earth. LRRRs or solar arrays left on the Moon by the Apollo astronauts. Jupiter marauds through the inner solar system, causing havoc, in its formative younger years. Saturn moves in, then pulls Jupiter out of its marauding in the inner solar system. Jupiter can also fling asteroids or comets on a path toward Earth, or, it can be a vacuum cleaner and suck up dangerous asteroids or comets that could eventually, or potentially, hit Earth. Contaminants on space mission. How NASA will protect astronauts from space radiation at the moon.

Recap of the Voyager mission from a PBS broadcoast from Wednesday August 1.

Joe Kittinger was the first human to jump from space to the Earth. It took bravado true bravado. KIittinger first went up in a balloon in the upper reaches of the atmosphere. then he jump from heights as high as 100,000 feet in free falls to Earth. He almost died once and on one mission, a leak in his spacesuit caused his hand to swell up to several times its size. He also fell unconsious once on a dive. His dives were necessary so that NASA could test the effect of radiation, and of being in space, on the human body. Jon Kittinger: a true pioneer, hero and brave man.
