Will a bright comet adorn our early spring sky? Why astronomers are getting excited about Comet C/2026 A1 (MAPS)
A new comet approaching the sun has caught the attention of astronomers, primarily because of its lineage. It appears to belong to a group of comets that in some cases have briefly become outstandingly bright objects.
James Webb Space Telescope's view of 800,000 galaxies paints a detailed picture of dark matter
Astronomers used James Webb Space Telescope data to determine the density of the universe's most mysterious "stuff."
Virginia Trimble, Memory Keeper of Modern Astronomy
Virginia Trimble collected "shiny things" in astronomy — and her curated collections fascinated astronomers around the world.
Turning Forgotten Telescope Data into New Discoveries
Astronomers have been collecting data for generations, and the sad fact is that not all of it has yet been fully analyzed. There are still discoveries hiding in the dark recesses of data archives strewn throughout the astronomical world. Some of them are harder to access than others, such as actual physical plates containing star positions from more than a hundred years ago. But as more and more of this data is archived, astronomers also keep coming up with ever more impressive tools to analyze it. A recent paper from Cyril Tasse of the Paris Observatory and his co-authors, published recently in Nature Astronomy describes an algorithm that analyzes hundreds of thousands of previously unknown data points in radio telescope archives - and they found some interesting features in it.
Did astronomers see a black hole explode? An 'impossible' particle that hit Earth in 2023 may tell us
"If our hypothesized dark charge is true, then we believe there could be a significant population of primordial black holes, which would be consistent with other astrophysical observations, and account for all the missing dark matter in the universe."
NASA's Artemis II Spacecraft on the Launch Pad
In this photo, the Artemis II mission's Orion spacecraft is shown positioned on Launch Pad 39B at NASA's Kennedy Space Center in Cape Canaveral, Florida. The image shows the second stage, comprising the Orion Crew Module, the European Service Module, the Launch Abort System, and the spacecraft adapter, all enclosed by the second-stage panels. Just visible beneath is the upper section of the Space Launch System (SLS), NASA's next-generation super-heavy launch vehicle that will send crewed spacecraft and payloads beyond Low Earth Orbit (LEO) in the near future.
It's time to think about human reproduction in space, scientists urge
"If reproduction is ever to occur beyond Earth, it must do so with a clear commitment to safety, transparency and ethical integrity."

Watch dead neutron stars smash together in new NASA supercomputer simulation
"We studied the last several orbits before the merger, when the entwined magnetic fields undergo rapid and dramatic changes, and modeled potentially observable high-energy signals."
Star Trek needs to go back to 20+ episode seasons — and there's never been a better time
It is time for Star Trek to boldly go where no streaming series has gone before: back to the 20+ episode seasons of old!
Cosmic Collision: The JWST Found An Early 5-Galaxy Merger
The JWST has spotted a system of five merging, interacting galaxies only about 800 million years post Big-Bang. This is sooner than astronomers thought, and is another example of the powerful space telescope forcing us to reconsider our understanding of the early Universe.
