Betelgeuse keeps getting dimmer and everyone is wondering what exactly that means. The star will go supernova at the end of its life, but that’s not projected to happen for tens of thousands of years or so. So what’s causing the dimming?

Never seen Neptune? It’s time you should, and this weekend offers a fine time to try, as the faintest planet in the solar system approaches the brightest in the dusk sky, for a splendid conjunction of the pair.

The United States Space Force has given us a look at their new uniforms, and critics are savaging them on Twitter and elsewhere. That’s because the new uniforms are camouflage.

For fans and enthusiasts of space exploration, the name Kevin Gill ought to be a familiar one. As a software engineer at NASA’s Jet Propulsion Laboratory who specializes in data visualization and analysis, he has a long history of bringing space exploration to life through imagery. Among his most recent offerings is a very interesting pic taken by the Curiosity rover early in its mission.

The world’s largest and most sensitive radio telescope is officially open for business according to Xinhua, China’s official state-run media. The FAST Radio Telescope saw fist light in 2016 but has been undergoing testing and commissioning since then. FAST stands for Five-hundred meter Aperture Spherical Telescope.

NASA and the NOAA just announced that 2019 was the second hottest year on record. It barely edged out 2016, the previous warmest year. And both 2019 and 2016 are part of the global warming trend: the last five years have been the warmest five years on record. And the last decade was the warmest decade.

At Launch Complex 39A at the Kennedy Space Center in Cape Canaveral, Florida, during the morning hours this past Sunday (Jan, 19th), SpaceX conducted the final uncrewed test of their Crew Dragon space capsule. This was the all-important in-flight abort test, the purpose of which was to validate the crew capsule’s escape capabilities in the event of an unexpected emergency during launch.
The event, which was live-streamed by NASA TV, was a complete success and saw the Crew Dragon successfully separate from its Falcon 9 launcher before being retrieved at sea. With this test complete, NASA and SpaceX will be moving forward with the first crewed mission. Known as Crew Demo-2, this mission will see two astronauts launched aboard the Crew Dragon to the International Space Station (ISS) later this year.

At the center of our galaxy lies a region where roughly 10 million stars are packed into just 1 parsec (3.25 light-years) of space. At the center of this lies the supermassive black hole (SMBH) known as Sagittarius A*, which has a mass of over 4 million Suns. For decades, astronomers have been trying to get a better look at this region in the hopes of understanding the incredible forces at work and how they have affected the evolution of our galaxy.
What they’ve found includes a series of stars that orbit very closely to Sagittarius A* (like S1 and S2), which have been used to test Einstein’s Theory of General Relativity. And recently, a team from UCLA’s Galactic Center Orbits Initiative detected a series of compact objects that also orbit the SMBH. These objects look like clouds of gas but behave like stars, depending on how close they are in their orbits to Sagittarius A*.

As part of their Commercial Crew Development (CCDev) Program, NASA has contracted with aerospace giants like SpaceX and Boeing to provide commercial launch services to the International Space Station (ISS). These services will consist of SpaceX’s Crew Dragon (Dragon 2) and Boeing’s CST-100 Starliner bringing astronauts to orbit in the coming years, effectively restoring domestic launch capability to the US.
To get these spacecraft ready for flight, Boeing and SpaceX have been putting them through rigorous launch tests. Tomorrow morning (Saturday, Jan. 17th), SpaceX will be conducting its final test in preparation for crewed flights. This is the all-important in-flight abort test, which will be live-streamed by NASA TV – will take place at 7:45 AM EST (4:45 AM PST) from Launch Complex 39A in Florida.
