Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results of the observations, published June 15 in a special issue of Galaxies journal, yield important insights into the morphology and kinematics of this […]

As humans, we live out our lives on a planet that is constantly sweeping through a cosmic ocean littered with ancient debris from the formation of the solar system. For the most part, our world glides silently through space, shielded by Earth’s thin atmosphere.

A stunningly concentrated and hefty galaxy cluster, from a time in the universe’s history when such massive structures aren’t expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of three recent papers, a team led by researchers from IPAC—a science and data center for astrophysics and planetary science at Caltech—have […]

A biocontainment facility designed to protect Earth from potentially hazardous biotic contaminants from space should be part of a planned NASA base on the moon, a policy paper maintains.

Sending a spacecraft to the underexplored planet Uranus is at the top of many planetary scientists’ wish lists. But which spacecraft-mounted instruments would be most useful for answering questions about the mysterious ice giant?

Southwest Research Institute (SwRI) scientists studying the inner main-belt asteroid Donaldjohanson have found that its rotation wobbles. Rather than rolling through space in a steady pattern, Donaldjohanson turns on two axes, rotating end over end once every 10.5 Earth days while wobbling around its horizontal axis every 26.5 days. The findings are published in the […]

A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star’s detonation sent its binary companion hurtling through space, and then, after traveling for thousands of years, the surviving star blew up, too.

Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life. In fact, the star may have produced elements on the periodic table all the way up to iron. As it exploded, it spewed these elements […]
