High-energy trap in our galaxy's center, revealed by gamma-ray telescopes

Science Daily Astronomy - Tue, 2017-07-18 14:29
The center of our Milky Way contains a 'trap' that concentrates some of the highest-energy cosmic rays, among the fastest particles in the galaxy, a combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System, a ground-based observatory in Namibia, suggests.

New brown dwarf discovered by citizen science project

Science Daily Astronomy - Mon, 2017-07-17 15:09
One night three months ago, Rosa Castro finished her dinner, opened her laptop, and uncovered a novel object that was neither planet nor star. Therapist by day and amateur astronomer by night, Castro joined the NASA-funded Backyard Worlds: Planet 9 citizen science project when it began in February -- not knowing she would become one of four volunteers to help identify the project's first brown dwarf, formally known as WISEA J110125.95+540052.8.

Hubble spots a barred Lynx spiral

Science Daily Astronomy - Fri, 2017-07-14 18:31
Discovered by British astronomer William Herschel over 200 years ago, NGC 2500 lies about 30 million light-years away in the northern constellation of Lynx. NGC 2500 is a particular kind of spiral galaxy known as a barred spiral, its wispy arms swirling out from a bright, elongated core.

Complex gas motion in the centre of the milky way

Science Daily Astronomy - Thu, 2017-07-13 16:54
Our solar system is located in the outer regions of the Milky Way, a disk-shaped galaxy with an approximate diameter of 100,000 light years. From Earth, its appearance can only be observed indirectly, by measuring positions and movements of stars and gas clouds. In addition to luminous stars, a substantial portion of the visible matter in our Milky Way is interstellar gas. Gas clouds in the so-called central molecular zone (CMZ) -- the innermost 1,500 light years of the Milky Way -- move on an elliptical central disk that has two spiral arms. A comprehensive model has now been used to simulate this motion.

Yes, the sun is an ordinary, solar-type star after all

Shedding light on Galaxies' rotation secrets

Science Daily Astronomy - Thu, 2017-07-13 15:48
Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. In a new study, the researchers have traced back the dichotomy in the angular momentum of spiral and elliptical galaxies to their different formation history. In particular, the low angular momentum of ellipticals is mainly originated by nature in the central regions during the early galaxy formation process.
