NASA shuts off Voyager 2 science instrument as power dwindles
NASA has turned off one of Voyager 2's science instruments as power conservation becomes crucial for the interstellar exploring spacecraft located 12.8 billion miles from home.
Get Ready for Comet Tsuchinshan-ATLAS — The Best Is Yet to Come!
Comet Tsuchinshan-ATLAS has delighted observers already, but its morning run was only a warm-up — wait till you see what's coming.

The European Space Agency is on the cusp of launching its first planetary defense mission, a complement to NASA’s 2022 Double Asteroid Redirection Test (DART) mission. The goal of these missions is to understand how Earth can be protected from a potentially destructive asteroid strike.
October's new moon will bring us a spectacular 'ring of fire' eclipse
October's new moon will occur today (Oct. 2) and create a dazzling annular solar eclipse.
Bernard's Star Has a Planet (Again)!
The thing about exoplanets is that astronomers don’t see them the way most people think they do. Part of the reason for that is the way we announce them. Whenever an interesting exoplanet is discovered, the press release usually has colorful artwork showing oceans, mountains, and clouds. Something visually captivating like the image above. But the reality is that we have only imaged a few exoplanets directly, and even then, they appear only as small fuzzy blobs. Most of the known exoplanets were discovered by the transit method, where the star dims slightly as the planet passes in front of it. So what astronomers actually see is a periodic flickering of starlight.
Did a NASA telescope detect cosmic 'hot dogs' or Dyson spheres?
The potential detection of "Dyson spheres" indicating advanced alien civilizations may actually be supermassive black hole powerful galaxies obscured by dusty shrouds called "hot DOGs."
'I think it was hard not to watch that rocket lift off without thinking, that's my rocket and that's my crew.' How the NASA astronauts bumped from SpaceX's Crew-9 watched their ride launch without them
NASA astronauts Zena Cardman and Stephanie Wilson were expected to launch on SpaceX's Crew-9 mission on Sept. 28. Still on Earth, they spoke about how they're feeling.
Uplifting news! ESA crowns new deep space antenna in Australia
This September saw the completion of a critical milestone for the construction of ESA's new deep space communication antenna in New Norcia, Australia: the lifting of the 122-tonne reflector dish.
Annular solar eclipse will turn the sun into a glorious 'ring of fire' today. Here's what you need to know.
Today (Oct. 2), the moon and sun will create a "ring of fire" during an annular solar eclipse. Here's how and when to catch the spectacular phenomenon.
An Earth-like Planet Around a Dead Sun Provides Some Reassurance About the Future of Earth
In about five billion years, our Sun will exit its main sequence phase and transition to its red giant phase. At this point, the Sun will expand and consume the planets of the inner Solar System, including Mercury and Venus. What will become of Earth when this happens has been the subject of debate for many decades. But with the recent explosion in exoplanet discoveries, 5,759 confirmed in 4,305 systems so far, astronomers hope to learn more about how planets fare as their stars near the end of their life cycle.
We Don’t See Many Planets in Old Triple Star Systems
Why is it important to search for exoplanets in triple star systems and how many can we find there? This is what a recent study accepted by Astrophysics & Space Science hopes to address as a pair of researchers from the University of Texas at Arlington investigated the statistical likelihood of triple star systems hosting exoplanets. This study holds the potential to help researchers better understand the formation and evolution of triple star systems and whether they are suitable to find life as we know it.
