Cosmic dark matter web detected in Coma cluster

The Subaru Telescope has spotted the terminal ends of dark matter filaments in the Coma cluster stretching across millions of light years. This is the first time that strands of the cosmic web spanning the entire universe ...

What the next solar maximum means for you

Much like the Earth, our sun is a dynamic body with a complex—and sometimes violent—weather system. Solar storms eject highly energetic radiation that can impact our planet, forming strong auroras and disrupting power ...

Old stars may be the best places to search for life

Once upon a cosmic time, scientists assumed that stars apply an eternal magnetic brake, causing an endless slowdown of their rotation. With new observations and sophisticated methods, they have now peeked into a star's magnetic ...

Webb finds signs of possible aurorae on isolated brown dwarf

Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. ...

NASA's Hubble watches 'spoke season' on Saturn

Though Saturn's unusual-looking "cup handle" features were first noted by Galileo in 1610, it would be another 45 years before they were described by Christiaan Huygens as a disk surrounding Saturn. Subsequently, ground-based ...

Fermi mission creates 14-year time-lapse of the gamma-ray sky

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA's Fermi Gamma-ray Space Telescope. Our sun, occasionally flaring into prominence, serenely traces a path through the sky against ...
