Hubble captured the closest supernova explosion in Nearby Galaxy M82

Hubble Space Telescope captured a supernova explosion named SN 2014J in the galaxy M82. The distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. The explosion is categorized as a Type Ia supernova, which is theorized to be triggered in binary systems consisting of a white dwarf and another star — which could be a second white dwarf, a star like our Sun, or a giant star.

Astronomers confirmed the disappearance of star in flash supernova

Researchers from several American scientific centers, including university of California, presented results of supervision over a place of flash of supernova M51 in a galaxy. Supervision was conducted with help of Hubble telescope, rather small automatic telescope on a surface of planet. Flash of the supernova was noticed on May 31, 2011 and it was seen only by owners of big telescopes as visible brightness of a star reached only to 12. Astronomers received a range of radiation supernova and by absence in it characteristic lines of hydrogen determined accident type: IIb. It means, that the disappearance of star was with a certain partner, who drew on itself considerable part of a hydrogen cover then the part, which has remained and consisting mainly from helium.

Astronomers Discovered Absolutely New Type of Mini Supernova

The opening was done by the astronomers from the Harvard-Smithsonian Center of Astrophysics by led of astronomer Rayan Foley. Earlier this type was unknown. The supernova received Iax designation. Unlike all other types the supernova explosion was so weak that astronomers hardly noticed it. The found supernova of this type called “mini supernova”. According to astronomers the material from the blue hot star consisting mainly of such chemical elements as helium, falls into the dwarfish star consisting of oxygen and carbon.

WISE Catches Aging Star Erupting With Dust

Astronomers by using images from NASA’s Wide-field Infrared Survey Explorer (WISE) reveal an old star in the throes of a fiery outburst, spraying the cosmos with dust. The findings offer a rare, real-time look at the process by which stars like our sun seed the universe with building blocks for other stars, planets and even life. The star, catalogued as WISE J180956.27-330500.2, was discovered in images taken during the WISE survey in 2010, the most detailed infrared survey to date of the entire celestial sky.

Hubble Space Telescope Shows Heart of Tarantula Nebula

New photo from the Hubble Space Telescope has captured an unprecedented panoramic view of the Tarantula nebula, revealing its bright heart of massive stars. The photo is actually a colossal mosaic, one of the largest ever built from Hubble images, and shows an intense star-forming hotspot called 30 Doradus. Hubble’s science team unveiled this new image on April 17. Hubble’s new view of the region inside the Tarantula nebula shows massive stars’ winds carving cavities into gas clouds, creating a fantasy landscape of pillars, ridges and valleys.

The Universe Expansion is Accelerating

The universe’s expansion is accelerating, an observation that prompted astronomers to invoke an unknown entity called dark energy to explain it, has been further confirmed by new measurements. Scientists have used cosmic magnifying glasses called gravitational lenses to observe super-bright distant galaxies, giving a measure of how quickly the universe is blowing up like a giant balloon. They found, in agreement with previous measurements, that the universe’s expansion is indeed speeding up over time.

Galaxy NGC 3810

New study finds that supernova explosions and the jets of a monstrous black hole are scattering a galaxy’s star-making gas like a cosmic leaf blower. The findings, which relied on ultraviolet observations from NASA’s Galaxy Evolution Explorer and a host of other instruments, fill an important gap in the current understanding of galactic evolution. It has long been known that gas-rich spiral galaxies like our oun smash together to create elliptical galaxies such as the one observed in the study.

Supernova Explosion Turned Left Over Stellar Corpse Inside Out

According to scientists massive supernova explosion that destroyed a faraway star apparently turned the left over stellar corpse inside out as well. Using NASA’s Chandra X-ray Observatory spacecraft, a team of researchers mapped the distribution of elements in the supernova remnant Cassiopeia A (Cas A for short) in unprecedented detail. They found that Cas A, which is located about 11,000 light-years from Earth and exploded 300 years ago from our perspective, is wearing its guts on the outside.
