Enlarge / From left to right, zooming in from the globular cluster to the location of the black hole. ESA/Hubble & NASA, M. Häberle Supermassive black holes appear to reside at the center of every galaxy, and have done so since galaxies formed early in the history of the universe. However, we currently cannot fully … Read more
Fuzzy new photos of a mountain-sized asteroid, a ‘planet killer’ that recently reached its closest approach to Earth in more than a century have revealed a surprising new feature of the giant space rock: it has a secret mini-moon. Asteroid 2011 UL21 is a possibly dangerousnear-Earth object previously estimated to be anywhere from 1.1 to … Read more
A hellish planet with a “hot Jupiter” relatively close to Earth would probably smell like rotten eggs if we ever made the trip there, new data from the James Webb Space Telescope (JWST) reveals. HD 189733 b is a gas giant located about 64 light-years away in the constellation Vulpecula. It orbits extremely close to … Read more
A galaxy floating next to our own some 380,000 light-years from Earth could provide new clues in the 90-year search for the nature of dark matter, the invisible glue that holds galaxies together. This mysterious substance accounts for more than 80% of the mass of the universe, but has not yet been directly observed. Scientists … Read more

The mysterious substance is responsible for more than 80% of the universe’s mass, but has yet to be directly detected. Scientists say … Read more
S-BGLS periodograms of YV2 for the star HD48948, focused on three frequency ranges (7.3, 38 and 151 d). The absolute value of log P has no meaning; instead, the relative values of log P have meaning. The signal observed at approximately 42 d in the middle panel represents the unstable activity feature. Credit: Monthly notices … Read more

Earth’s protective atmosphere has sheltered life for billions of years, creating a haven where evolution has produced complex life forms like us. The ozone layer plays a crucial role in protecting the biosphere from deadly UV radiation. It blocks 99% of the sun’s powerful UV rays. Earth’s magnetosphere also protects us. But the sun is … Read more
“The James Webb Telescope: Are We Alone?” about the whole story with Anderson Cooper offers a glimpse into the most powerful telescope ever built. The show premieres Sunday, June 16 at 8 PM ET/PT on CNN. A collision between giant asteroids has likely occurred in recent years in a neighboring galaxy called Beta Pictoris, and … Read more
NASA/FUSE/Lynette Cook An illustration shows colliding asteroids around the central star in the Beta Pictoris system and the formation of terrestrial planets. The insets show what two of the system’s planets might look like. “The James Webb Telescope: Are We Alone?” about the whole story with Anderson Cooper offers a glimpse into the most powerful … Read more
