Students from Arizona will have an opportunity this week to talk with a NASA astronaut on the International Space Station.

If humanity ever truly felt our existence threatened by an asteroid, we may not be able to smash the looming space rock into pieces after all.

This is our second episode in a two part series where we look at Transients in astronomy. In last week’s episode, we talked about things that change here in our own Solar System. Now we’ll talk about everything else ...

Scientists have long posited that periodic swings in Earth's climate are driven by cyclic changes in the distribution of sunlight reaching our surface. This is due to cyclic changes in how our planet spins on its axis, t...

Welcome to the 601st Carnival of Space! The Carnival is a community of space science and astronomy writers and bloggers, who submit their best work each week for your benefit. We have a fantastic roundup today so now, on...

On June 27th, 2018, the Japanese Aerospace Exploration Agency‘s (JAXA) Hayabusa2 spacecraft rendezvoused with the asteroid 162173 Ryugu. Carrying on in the same tradition as its predecessor, Hayabusa2 recently conducte...

It’s another milestone for SpaceX as their Crew Dragon spacecraft successfully docked with the International Space Station. In the early morning of March 2nd, the unmanned Crew Dragon launched from complex 39A at NASA�...

NASA's current slogan is "Forward To The Moon". They say this because they do not want to say "Back To The Moon" Isn't about time for NASA to speak boldly about what it plans to do?...

The launch of SpaceX's first Crew Dragon space capsule to the International Space Station did more than just advance the day when astronauts will again fly into space from U.S. soil.

For almost a decade, astronomers have tried to explain why so many pairs of planets outside our solar system have an odd configuration--their orbits seem to have been pushed apart by a powerful unknown mechanism. Yale re...

Reviews of SpaceX and ULA, regardless of whether or how they might be connected, are a reminder of the dog-eat-dog world of military space launch. SpaceNews.com

On 28 February 2019, 'Mole' fully automatically hammered its way into the Martian subsurface for the first time. In a first step, it penetrated to a depth between 18 and 50 centimetres into the Martian soil with 4000 ham...

In preparation for the new multi-object survey spectrograph, WEAVE, on the 4.2m William Herschel Telescope, the astronomical community is working on deep imaging surveys to identify the astronomical objects that will be ...

Using a network of radio telescopes, European astronomers have investigated a decade-long transient known as FIRST J141918.9+394036. Results of this study, presented in a paper published February 18 on arXiv.org, provide...

Brown dwarfs are stars less massive than the sun and unable to burn hydrogen. They comprise (at least in mass) a bridge between planets and stars, and astronomers think that they form and evolve in ways different from ei...

This photograph, taken a short hike from the Geographic South Pole in Antarctica, shows some of the antennas comprising the Super Dual Auroral Radar Network (SuperDARN) array. They are visible here as the chain of antenn...

More than 1800 years ago, Chinese astronomers puzzled over the sudden appearance of a bright "guest star" in the sky, unaware that they were witnessing the cosmic forge of a supernova, an event repeated countless times s...

People on Earth are familiar with the sun's powerful rays -- but the moon suffers from sunburn, too.

A distant alien world that was potentially on its way into exile in interstellar space was rescued by the gravitational pull of a passing pair of stars, a new study argues.
