A team of scientists found NASA's Nancy Grace Roman Space Telescope will be able to measure a specific kind of space dust littered throughout dozens of nearby planetary systems' habitable zones, or the regions around stars ...

More than 30 years ago the Infrared Astronomy Satellite discovered that the universe contained many almost invisible yet enormously luminous galaxies—some of them more than 1,000 times brighter than our own Milky Way. These ...

Star formation in the Milky Way primarily occurs in long, dense filaments of gas and dust that stretch along the spiral arms. Dubbed "bones" because they delineate the galaxy's densest skeletal spiral structures, these filaments ...

What was previously identified as a gas and dust cloud at the center of our galaxy actually consists of three very young stars. That is the result of a new study led by scientists from the University of Cologne's Institute ...

Stars are born from turbulent clouds of gas and dust that collapse under their own gravitational attraction. As the cloud collapses, a dense, hot core forms and begins gathering dust and gas, creating a protostar. This star-forming ...

This NASA Hubble Space Telescope image captures a portion of the reflection nebula IC 2631 that contains a protostar, the hot, dense core of a forming star that is accumulating gas and dust. Eventually the protostar may gravitationally ...

Planets form as the dust grains in a protoplanetary disk grow into pebbles and then finally into planets. Because small dust grains interact with gas (via the drag it imparts), the gas in protoplanetary disks influences the ...

When a star like our sun gets to be old, in another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining it will shrink to a fraction of its ...
