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
Engineers are currently busy making the first parts of what will eventually become the Gateway Space Station. One day, if all goes according to plan, Gateway will serve as the first lunar orbiting space station, and the moon’s first true transportation hub. While not intended to be permanently inhabited, the station is being built to … 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

Planets could survive the death of their star and be able to sustain life – and now astronomers are hunting for them. Stars don’t survive forever, the sun included. In about five billion yearsEarth’s star will begin to deplete its supply of hydrogen used to generate energy nuclear fusion at its core. The Sun’s core … Read more

An international team discovered an Earth-sized planet orbiting a long-lived red dwarf, providing unique insights into potentially habitable worlds. Credit: SciTechDaily.com Researchers using global robotic telescopes have discovered an Earth-sized planet, SPECULOOS-3 b, orbiting an ultracool red dwarf. Milky Way. This planet, which is confined and likely has no atmosphere due to its intense radiation, … Read more
Astronomers have discovered an Earth-sized planet that is receiving so much radiation that its atmosphere has long since eroded away, leaving it barren. Life as we know it cannot exist on this sizzling world, but astronomers are interested in it for another reason: for the first time, they may be able to see the geology … Read more
