Astronomers get first look at a baby planet being born

The twist at the center of the disc could be the location of a new planet one day. ESO/Boccaletti et al. Scientists are seeing signs that a new planet could be forming about 520 lightyears away from Earth.Images from the European Southern Observatory's Very Large Telescope (ESO's VLT) show a "dense disc of dust and…
Astronomers discover oldest disk galaxy ever hiding deep in the cosmos

Astronomers discover oldest disk galaxy ever hiding deep in the cosmos

The Wolfe Disk is a massive rotating disk from the earliest days of the universe. NRAO/AUI/NSF/S. Dagnello How do you build a galaxy? That's a question astronomers continue to ask themselves as they formulate theories on how these gargantuan systems, full of dust, gas and stars, come together. In seeking answers, they turn their telescopes…

Astronomers discover regular rhythms in mysterious pulsating stars

A screenshot of a simulation showing the pulsations of star HD 31901 Chris Boshuizen/Simon Murphy/Tim Bedding The stars speak! Understanding stars, including our own sun, has largely revolved around examining their outsides: the surfaces and surrounding atmospheres we can see. Although we can't look inside a star, we can listen to the rumbling it makes…

It might look like it's busy, but it's actually just taking it easy. NASA Without the sun's heat, Earth would be an ice-coated rock. It does a lot for us. But compared with other stars of its size, it turns out our sun, the literal light of our lives, is a bit of a deadbeat.…

The Very Large Telescope watched a star for 27 years, measuring its movements around Sagittarius A* at the center of the Milky Way ESO/L. Calçada The mammoth black hole at the center of the Milky Way, Sagittarius A* (or, in short, Sgr A*), is orbited by a veritable buffet of stars which are beholden to…

Earth, as seen from the Moon in 1968, could have pulled a new mini-moon into its gravity. Corbis via Getty Images We have a new space neighbor, at least for a while. Astronomers at the NASA-funded Catalina Sky Survey spotted an asteroid that's caught in Earth's gravity, but the space agency's Center for Near-Earth Objects…
