New solar cycle clock resolves timings of solar activity, revealing the long and the short of the Sun’s seasons. Research led by University of WarwickFounded…
Shown here in composite view, ALMA data (red/orange) reveals filament structures left behind by ram pressure stripping in a Hubble Space Telescope optical view of…
This illustration depicts a collapsing star that is producing two short gamma-ray jets. Just before a massive, collapsing star explodes as a supernova, we often…
Scientists have measured thousands of nearby stars and far away galaxies that have never been identified before at radio wavelengths, while studying a galactic body…
Scientists at SwRI developed this conceptual image of heavy ion dynamics based on MMS observations. The colored trajectory lines illustrate how alpha particles (He++) behave…
The COSMOS-Webb survey will map 0.6 square degrees of the sky—about the area of three full Moons—using the James Webb Space Telescope’s Near Infrared Camera…
During its 2013 flight, NASA’s EUNIS sounding rocket examined light from the Sun in the area shown by the white line (imposed over an image…
This illustration shows astronomers’ current understanding of the large-scale structure of the Milky Way. Stars and star-forming regions are largely grouped into spiral arms. Measuring…

Rice University scientists have shown that “cool” stars like the sun share dynamic surface behaviors that influence their energetic and magnetic environments. Stellar magnetic activity…
Artist’s impression of an inner accretion flow and a jet from a supermassive black hole when it is actively feeding, for example, from a star…
The illustration shows an aluminum-26 nucleus (green) escaping a supernova explosion. It will subsequently decay via gamma-ray emission that can be observed by satellites. Credit:…
An artist’s impression of an accretion disk rotating around an unseen supermassive black hole. The accretion process produces random fluctuations in luminosity from the disk…
