Astronomers capture first image of the black hole at the center of our Milky Way galaxy

Three years after the release of the first image of a black hole captured in another galaxy, astronomers are revealing the first image of what is believed to be the black hole at the center of our own galaxy.

Sagittarius A* (or Sgr A*, pronounced A-star) is an object 27,000 light-years from Earth that is four million times more massive than the Sun. The image of the object was created by the Event Horizon Telescope Collaboration based on eight radio telescopes around Earth.

What a solar eclipse looks like on Mars through the eyes of NASA’s Perseverance rover

You might have forgotten about Mars‘ two little moons. Smaller and not so circular, they aren’t as crazy as those found around Jupiter or Saturn. However, they are still special because we can see them pass in front of the Sun like our own, and through Perseverance, we can see Mars’ solar eclipses with better resolution than ever before.

NASA to test quantum experiment using the Nanoracks airlock on the ISS

NASA is set to launch a technology demonstrator payload that could have greater implications for quantum computing. Scheduled to launch in August, this technology demonstration will test two communications technologies that can pave the way for quantum computers to communicate with each other no matter where they’re located.

Mars 2020’s Perseverance Rover lands on the surface of Mars | This Day in Space (18 Feb. 2021)

How on Earth (err.. Mars?) has it been a full year since NASA’s latest Mars rover landed on the surface of Mars!

The rover launched back on July 30, 2020 on an Atlas V 541 rocket and traveled for over 200 days before landing on the surface of the Red Planet.

Starlink expanding, coming to Dragon capsule on Polaris Dawn, but NASA has concerns about the constellation

In a Tweet last year, Elon Musk confirmed that Starlink laser-based communication was coming to SpaceX’s Dragon capsule. Now we know the Polaris Dawn mission will be the first crew to test out and make use of this additional connectivity option. And as Starlink continues to expand, with plans for Gen2 Starlink satellites launched on Starship being essential for the company, NASA has expressed some concerns about the expanding constellation.

US or China: Whose rocket is about to hit the Moon?

News sites around the world, including us, reported on a Falcon 9 upper stage that was on a collision course with the Moon, with an impact expected on March 4. Except… new evidence (or rather, reobserving old evidence) points to the fact that this rocket stage is not actually the Falcon 9 upper stage from the DSCOVR mission, but instead a rocket stage from the Long March 3C that launched China’s Chang’e 5-T1 mission.

Easily track the SpaceX rocket stage headed for the Moon with a Unistellar eVscope

When Bill Gray and a team of observers realized that the SpaceX Falcon 9 upper stage that launched the DSCOVR mission is going to crash into the Moon, everyone was talking about it. Now, Unistellar is making it easy for citizen astronomers to catch a glimpse of the rocket with their eVscopes, before it crashes into the Moon on March 4.

Astronomers discover dwarf planet Eris, sparking Pluto debate | This Day in Space (5 Jan. 2005)

On January 5, 2005, the Palomar Observatory-based team led by Mike Brown discovered a large world, later known as Eris, after systematically scanning for large outer Solar System bodies for several years. Unfortunately for Pluto, this was the beginning of the end for its official planet title.

How to track James Webb Space Telescope, mission timeline

Currently, more than 35,000 miles away, the James Webb Space Telescope (JWST) is cruising through space on the way to its 1 million mile parking spot above the Earth. It will take the space telescope almost a month to complete orbital insertion. Here’s how you can track its way there.

FINAL UPDATE (1/31): James Webb is now fully deployed and orbiting in L2. The space telescope will spend the next few months commissioning and testing before taking its first photograph. Last week, NASA announced that Webb will point at HD 84406, a sun-like star 241 light-years away, to focus and align its mirrors in preparation for the moment we’ve been waiting for. Don’t hold your breath though, the mirror alignment process is very slow and tedious. We don’t expect James Webbs to take its first shot of the cosmos until around May 2022.
