Most Energetic Light ever Observed from a Few Kilometers Large Star

The neutron star (red sphere) with its strong magnetic field (white lines) spins around itself nearly 30 times per second injecting energetic electrons in the space region around it. The green and blue shaded regions depict different particle acceleration zones from where the detected photons could originate. The green zone lies in the vicinity of the pulsar's magnetosphere, whereas the blue zone could be as far as 100,000 km away from the pulsar. Credit: Patricia Carcelén Marco

Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) observatory has found the most energetic pulsed emission radiation ever detected from the neutron star in the center of the supernova of 1054 A.D. ie Crab pulsar. It is the corpse left over when the star that created the Crab nebula exploded as a supernova...

Features on dwarf planet Ceres that piqued the interest of scientists throughout 2015 stand out in exquisite detail in the latest images from NASA’s Dawn spacecraft, which recently reached its lowest-ever altitude at Ceres. Dawn took new images near its current altitude of 240 miles from Ceres, between Dec. 19 and 23, 2015.

Kupalo Crater, one of the youngest craters on Ceres, shows off many fascinating attributes at the high image resolution of 120 feet per pixel. The crater has bright material exposed on its rim, which could be salts, and its flat floor likely formed from impact melt and debris. Researchers will be looking closely at whether this material is related to the “bright spots” of Occator Crater...

The Formation of Carbon-Rich Molecules in Space

The space between stars is not empty, but contains an abundance of diffuse material, about 5-10% of the total mass of our galaxy (excluding dark matter). Most of the material is gas, predominantly hydrogen, but with a small and important component in complex carbon-bearing molecules including ethene, benzene, propynal, methanol and other alcohols, cyanides, simple amino acids, and even larger molecules (polycyclic aromatic hydrocarbons and buckyballs) with 50 or more carbon atoms...

Hubble sees a Supermassive and Super-Hungry Galaxy

Hubble sees a supermassive and super-hungry galaxy

Spiral galaxy NGC 4845 is seen >65 million light-years away in the constellation of Virgo. The galaxy’s orientation clearly reveals the galaxy’s striking spiral structure: a flat and dust-mottled disk surrounding a bright galactic bulge. NGC 4845’s glowing center hosts a gigantic version of a black hole, known as a supermassive black hole. The presence of a black hole in a distant galaxy like NGC 4845 can be inferred from its effect on the galaxy’s innermost stars; these stars experience a strong gravitational pull from the black hole and whizz around the galaxy’s center much faster than otherwise.

From investigating the m...
