Rare extreme helium star identified by astronomers

(Phys.org)—Astronomers have identified another rare example of an extreme helium star. The star, designated GALEX J184559.8−413827 (or J1845−4138 for short), was initially classified as a faint helium-rich "hot subdwarf," ...

A unique data center for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have established 'Cosmowebportal', a unique data center for cosmological simulations located at the Leibniz Supercomputing Centre ...

New branch in family tree of exoplanets discovered

Since the mid-1990s, when the first planet around another sun-like star was discovered, astronomers have been amassing what is now a large collection of exoplanets—nearly 3,500 have been confirmed so far. In a new Caltech-led ...

Probing the possibility of life on super-Earths

Along with its aesthetic function of helping create the glorious Aurora Borealis, or Northern Lights, the powerful magnetic field surrounding our planet has a fairly important practical value as well: It makes life possible.

The anatomy of Orion

The Orion molecular cloud is a large complex of hot young stars, nebulae, and dark clouds of gas and dust located in the constellation of Orion. Two particularly famous sights in the night sky, the Orion Nebula and the Horsehead ...

Image: A stormy stellar nursery

This shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud.

CTA prototype telescope, ASTRI, achieves first light

During the nights of 25 and 26 May, the camera of the ASTRI telescope prototype recorded its first ever Cherenkov light while undergoing testing at the astronomical site of Serra La Nave (Mount Etna) in Sicily managed by ...

VST captures three-in-one

Two of the sky's more famous residents share the stage with a lesser-known neighbour in this enormous new three gigapixel image from ESO's VLT Survey Telescope (VST). On the right lies Sharpless 2-54, the iconic Eagle Nebula ...
