The cool white dwarf WDJ1330+6435 has accreted sodium-rich rocky material from its planetary system into its atmosphere. The immense atmospheric density causes the sodium to absorb light over broad range of yellow, orange, and red wavelengths, giving the WDJ1330+6435 a ghostly green…
The legendary Hubble Space Telescope, operated by NASA and the European Space Agency (ESA), captured a dazzling snapshot of a large galaxy (NGC 169) pulling cosmic material away from a smaller galaxy (IC 1559). "As common as these interactions are thought to…
When we look across the Universe, we might come to the conclusion that intelligent life is really a very rare thing indeed For as long as humanity has looked up at the stars, we have wondered whether someone, somewhere, might…
The Milky Way’s central black hole could lose mass by powering escaping particles, and new calculations suggest how astronomers might detect the process. Most of the intense radiation associated with actively feeding black holes originates from surrounding matter rather than…
Every piece of equipment that comes our way, whether a camera, a lens or an accessory, gets the same level of careful scrutiny. We discover what products are good at and what they are not so you don’t have to.
However, exactly when, during the process of matter consumption, the black hole emits a jet was unpredictable–until now. Further, those conditions appear to apply to both medium-sized black holes found around the Milky Way, and the supermassive black holes…
Astronomers discovered that WASP-17b has an uneven atmosphere, with extreme temperature differences between its morning and evening sides. Planets appear as perfectly round disks when they cross in front of their stars, and astronomers have long measured them that way.
A retired RAF fighter pilot called Wing Commander Andy Green proved that speed doesn’t kill. In 1997, in the Black Rock Desert in Nevada, USA, he drove the world’s fastest car, ThrustSSC, at an incredible speed of 763.035 mph, which not only…
Like the surface of an ocean, the fabric of the Universe is constantly rippling with an infinitude of gravitational waves, propagating outward across the cosmos. We can count, in triple digits, the number of these ripples we've detected to date…
October 17, 2026 2:41 AM / Staff Report A Cornell-led science team is preparing a new telescope high in Chile's Atacama Desert for its first observations, a step toward studying galaxy clusters, the early universe and the Milky Way with instruments built in part…
