NASA's Goddard Space Flight Center: As far as galaxies are concerned, size can be deceptive. Some of the largest galaxies in the Universe are dormant, while some dwarf galaxies, such as ESO 553-46 imaged here by the NASA...

A new study by an international team of scientists has found a connection between debris disks and giant planets, which could aid in the hunt for exoplanets. The post Debris Disks Around Stars Could Point the Way to Gian...

The U.S. Defense Innovation Unit Experimental (DIUx), a Pentagon team charged with finding cutting-edge technologies to solve pressing national security problems, is not likely to abandon efforts to obtain radar data and...

When the total solar eclipse swept across the United States on Aug. 21, 2017, NASA satellites captured a diverse set of images from space. But days before the eclipse, some NASA satellites also enabled scientists to pred...

The U.S. Federal Communications Commission is still sifting through industry ideas for opening satellite-dominated C-band spectrum to terrestrial telecommunications, and while not yet reaching a conclusion, considers Int...

This week's link to headlines around the world on the threats, opportunities, and dangers facing our fragile planet --along with an occasional dash of humor, popular culture, and intriguing conspiracy. Asteroid 2012 TC4 ...

Combining computer observations and simulations, a new model shows that the presence of neutrals in the gas facilitates the magnetic fields to penetrate through the surface of the Sun producing the spicules. In this stud...

While NASA and the Department of Energy (DOE) have restarted production of a plutonium isotope used to power some space missions, a new report warns of challenges that could threaten its long-term supply.

The quest to discover how planets found in the far reaches of the universe are born has taken a new, crucial twist.
