For years, astronomers have worried about how to explain why the Milky Way has fewer satellite galaxies than the standard dark matter model predicts. This is called the "missing satellites problem."

Astronomers concluded it is not the same and that Cassini's spot disappeared in 1708.

From the coldest planets to spacecraft that have exited the Solar System, these little-known facts stump even many professional astronomers.

Using the James Webb Space Telescope (JWST), astronomers from the Space Telescope Science Institute (STScI) have discovered a new supernova. Designated SN 2023adsy, the newfound stellar explosion is the most distant Type Ia supernova so far detected. The finding was detailed in a research paper publ...

Using the joint NASA, European Space Agency (ESA), and Canadian Space Agency (CSA) James Webb…

Just months after Neil Armstrong’s historic moonwalk, Jim Storer, a Lexington High School student in Massachusetts, wrote the first Lunar Landing game. By 1973, it had become “by far an…

Voyager 1 remains undefeated.

Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts say.

The reversal could have a beneficial effect on Earth.

Days after light shows filled Earth’s skies with wonder, the red planet was hit by another powerful outburst of the sun.

Nine members of Congress have asked NASA to reconsider proposed budget cuts for the Chandra X-Ray Observatory.

The Webb and Gaia telescopes have unearthed the early building blocks of the Milky Way.

New images of Jupiter's volcano-studded moon Io, taken by the Large Binocular Telescope on Mount Graham in Arizona, offer the highest resolution of Io ever achieved with an Earth-based instrument. The observations were made possible by a new high-contrast optical imaging instrument, dubbed SHARK-VIS...

"We do not see Hubble as being on its last legs."

In May 1989, NASA launched its Magellan mission to Venus with the goal of mapping…

How can machine learning help astronomers find Earth-like exoplanets? This is what a recently accepted study to Astronomy & Astrophysics hopes to address as a team of international researchers investigated how a novel neural network-based algorithm could be used to detect Earth-like exoplanets using...

"Its discovery has profound implications."

The shape of the cosmos could be much more complex than anyone had ever imagined

An amazing photo from an aging spacecraft.

Editor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process.

A giant stellar explosion is going to be visible from Earth. Here's how to see it.

"Euclid’s instruments can detect objects just a few times the mass of Jupiter."

The most iconic, longest-lived space telescope of all, NASA's Hubble, is experiencing orbital decay as the solar cycle peaks. Here's why.

The sun’s powerful magnetic field has long puzzled scientists. A new study suggests the source of its magnetic field is nearer the surface than first thought.

Webb wows us again.

An international team led by researchers at Oxford University Physics have proved Einstein was correct about a key prediction concerning black holes. Using X-ray data to test Einstein’s theory of gravity, their study gives the first observational proof that a “plunging-region” exists around black ho...

So far disruptions from the geomagnetic storm appear to be manageable.

Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.  Renyu Hu from NASA’s Jet Pro...

Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" black holes that has so far eluded detection.

First light for the Vera Rubin Observatory (VRO) is quickly approaching and the telescope is reaching milestone after milestone. A few weeks ago, the observatory announced that its digital camera, the largest one ever made, is complete. Now the observatory has announced that its unique primary/terti...

Curiosity discovered manganese oxide in bedrock in a Martian region that may have been a shoreline billions of years ago.

Enterobacter bugandensis is primarily found in clinical specimens including the human gastrointestinal tract.

The solar flare is the most powerful eruption from sunspot region R3654 yet.
