3D print a piece of Mars for the holidays
There’s a galaxy of gifts out there for space nerds. Researchers at The University of Texas at Austin may have just the thing to set your present apart: a model of Jezero Crater, the landing site of NASA’s upcoming Mars…
A Galactic Dance
Galaxies lead a graceful existence on cosmic timescales. Over millions of years, they can engage in elaborate dances that produce some of Nature’s most exquisite and striking grand designs. Few are as captivating as the galactic duo known as NGC 5394/5, sometimes nicknamed the Heron Galaxy. This image, obtained by the Gemini Observatory of NSF’s National Optical-Infrared Astronomy Research Laboratory, captures a snapshot of this compelling interacting pair.

One step closer to living on Mars: NAU scientists contribute to NASA’s ‘treasure map’ of widespread water ice near planet’s surface
Northern Arizona University professor Christopher Edwards and postdoc Jennifer Buz are co-authors of a study published this week in Geophysical Research Letters that mapped several locations on Mars at high and mid-latitudes where water ice exists at a depth as little as an inch below the planet’s surface.
OU research group confirm planet-mass objects in extragalactic systems
NORMAN, OKLA. – A University of Oklahoma research group is reporting the detection of extragalactic planet-mass objects in a second and third galaxy beyond the Milky Way after the first detection in 2018. With the existing observational resources, it is…
NRL-camera aboard NASA spacecraft confirms asteroid phenomenon
WASHINGTON – A U.S. Naval Research Laboratory-built camera mounted on the NASA Parker Solar Probe revealed an asteroid dust trail that has eluded astronomers for decades. Karl Battams, a computational scientist in NRL’s Space Science Division, discussed the results from…
NSF grants Illinois-led team $4.4 million to develop distributed space telescope
More than 91 million miles from Earth, the sun poses a mystery that has long stumped scientists and defies the laws of thermodynamics: Why the corona, the sun’s outer layer, is 1000 times hotter than the layer beneath it. “Unraveling…

Stardust from red giants
Around 4.5 billion years ago, an interstellar molecular cloud collapsed. At its centre, the Sun was formed; around that, a disc of gas and dust appeared, out of which the earth and the other planets would form. This thoroughly mixed…

Yervant Terzian, who explored matter between stars, dies at 80
Yervant Terzian, the Tisch Distinguished Professor Emeritus in the Department of Astronomy at Cornell University, who studied the physical matter between stars, dedicated his career to education and chaired the department for two decades, died Nov. 25 in Ithaca. Terzian was 80.
OSIRIS-REx cameras capture particle ejection from asteroid Bennu
Cameras aboard NASA’s OSIRIS-REx spacecraft captured close-up shots of material being ejected from the surface of the near-Earth asteroid Bennu. The images offer a detailed look at small-scale mass loss events on an active asteroid, whereas before, observations have been…
