The Milky Way’s supermassive black hole, called Sagittarius A* (or Sgr A*), is arrowed in the image made of the innermost galactic center in X-ray light by NASA’s Chandra Observatory.
It’s a well-documented fact that roughly 4 billion years ago, Mars had liquid water flowing on its surface.
Hydrogen is the most abundant element in the Universe. But here on Earth, it’s rather rare. That’s unfortunate, because in our warming world, its status as an emissions-free fuel makes it a coveted chemical.
This week, from March 20th to 24th, the 48th Lunar and Planetary Science Conference will be taking place in The Woodlands, Texas.
Upgraded SpaceX Falcon 9 blasts off with Thaicom-8 communications satellite on May 27, 2016 from Space Launch Complex 40 at Cape Canaveral Air Force Station, FL.
To kids, there are only two kinds of dinosaurs: meat-eaters and plant-eaters. But to paleontologists, those are just diet distinctions.
Mount Etna is Europe’s most active volcano, and it’s been spouting off since late February 2017. It spewed lava and gas with a rather big eruption last week, where 10 people were actually injured.
Since it landed on August 6th, 2012, the Curiosity rover has spent a total of 1644 Sols (or 1689 Earth days) on Mars.
Before we really get started on today’s episode, I’d like to share a bunch of really cool pictures created by my friend Kevin Gill.
As part of their effort to kick-start the eventual colonization of Mars, SpaceX is sending an unmanned Dragon spacecraft to Mars.
You gotta love Earth’s atmosphere. It basically makes life (as we know it) possible on our planet by providing warmth and air to breathe, as well as protecting us from nasty space things like radiation and smaller asteroids.
The Rosetta spacecraft learned a great deal during the two years that it spent monitoring Comet 67P/Churyumov-Gerasimenko – from August 6th, 2014 to September 30th, 2016.
Since it began its second operational run in 2015, the Large Hardon Collider has been doing some pretty interesting things.
This week’s Carnival of Space is hosted by Brad Rogers at The Evolving Planet blog. Click here to read Carnival of Space #501.
Stephen Hawking has spent decades theorizing about the Universe. His thinking on black holes, quantum gravity, quantum mechanics, and a long list of other topics, has helped shaped our understanding of the cosmos.
Orbital debris, otherwise known as “space junk”, is a major concern. This massive cloud that orbits the Earth is the result of the many satellites, platforms and spent launchers that that have been sent into space over the years.
The SpaceX Dragon CRS-10 spacecraft is pictured seconds before splashing down in the Pacific Ocean on Mar.
The period known as the Scientific Revolution (ca. 16th to the 18th century) was a time of major scientific upheaval.
We’ve posted several ‘flyover’ videos of Mars that use data from spacecraft. But this video might be the most spectacular and realistic.
Comet 41P Tuttle-Giacobini-Kresák glows green (left) and shows its true coma and just the hint of a stubby tail in the negative (red) image (right) from March 19th.
