NASA’s Spitzer Telescope Witnesses Asteroid Smashup

NASA's Spitzer Telescope Witnesses Asteroid Smashup

NASA’s Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.

Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013.

“We think two big asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now smashing themselves into smithereens and slowly leaking away from the star,” said lead author and graduate student Huan Meng of the University of Arizona, Tucson.

NASA Telescopes Uncover Early Construction of Giant Galaxy

Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.

NASA Telescopes Help Uncover Early Construction Phase Of Giant Galaxy

Astronomers have for the first time gotten a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a developing galaxy containing a dense core that is blazing with the light of millions of newborn stars which are forming at a ferocious rate. The discovery was made possible through combining observations from NASA’s Hubble and Spitzer space telescopes, the European Space Agency’s Herschel Space Observatory, and the W.M. Keck Observatory in Hawaii.

Because the infant galaxy is so far away, it is seen as it appeared 11 billion years ago, just 3 billion years after the birth of the universe in the big bang. Astronomers think the compact galaxy will continue to grow, possibly becoming a giant elliptical galaxy, a gas-deficient assemblage of ancient stars theorized to develop from the inside out, with a compact core marking its beginnings.

NASA’s Hubble Finds Supernova Star System Linked to Potential ‘Zombie Star’

NASA's Hubble Finds Supernova Star System Linked to Potential 'Zombie Star'

Astronomers using NASA’s Hubble Space Telescope for the first time have spotted a star system that later produced an unusual supernova explosion of a white dwarf, the stripped-down core of an ordinary star at the end of its life.

Examining archived Hubble images taken before the supernova, astronomers say they have detected the blue companion star of the white dwarf. The white dwarf slowly siphoned fuel from its companion, eventually igniting a runaway nuclear reaction in the dead star, and producing a weak supernova blast.

This particular supernova is classified as a Type Iax, a recently identified class of stellar explosion. These exploding stars are less energetic and fainter than Type Ia supernovae, which also originate from exploding white dwarfs in binary systems. Astronomers originally thought these weaker stellar blasts were unique Type Ia supernovae. So far, they have identified more than 30 of these mini-explosions, which occur at one-fifth the rate of Type Ia supernovae.
