The planet, called CoRoT-9b, was discovered by using the CoRoT space telescope satellite.

An international team of scientists, including several who are affiliated with UC Santa Barbara, has discovered a new planet the size of Jupiter. The finding is published in the March 18 issue of the journal Nature.

Super Supernova: White Dwarf Star System Exceeds Mass Limit

100315162049-large

Cosmologists use Type Ia supernovae, like the one visible in the lower left corner of this galaxy, to explore the past and future expansion of the universe and the nature of dark energy.

An international team led by Yale University has, for the first time, measured the mass of a type of supernova thought to belong to a unique subclass and confirmed that it surpasses what was believed to be an upper mass limit. Their findings, which appear online and will be published in an upcoming issue of the Astrophysical Journal, could affect the way cosmologists measure the expansion of the universe.

An international group of astrophysicists has determined that a massive planet outside our Solar System is being distorted and destroyed by its host star — a finding that helps explain the unexpectedly large size of the planet, WASP-12b.

Eta Cancri: Researchers in the UK and China recently discovered a binary pair of red stars — one giant, one dwarf.

A binary pair of red stars, one giant one dwarf, has been discovered by a collaboration of astrophysicists from the University of Hertfordshire and The Chinese Academy of Sciences.

Astronomers have found a giant magnetic loop stretched outward from one of the stars making up the famous double-star system Algol. The scientists used an international collection of radio telescopes to discover the feature, which may help explain details of previous observations of the stellar system.

Astronomers Capture First Direct Spectrum of an Exoplanet

100113104247-large

By studying a triple planetary system that resembles a scaled-up version of our own Sun’s family of planets, astronomers have been able to obtain the first direct spectrum of a planet around a star, thus bringing new insights into its formation and composition.

By studying a triple planetary system that resembles a scaled-up version of our own Sun’s family of planets, astronomers have been able to obtain the first direct spectrum — the “chemical fingerprint” [1] — of a planet orbiting a distant star [2], thus bringing new insights into the planet’s formation and composition. The result represents a milestone in the search for life elsewhere in the Universe.

First Super-Earths Discovered Orbiting Sun-Like Stars

This image from a simulation of atmospheric flow shows temperature patterns on one of the newly discovered planets (61Virb), which is hot enough that it glows with its own thermal emission.

An international team of planet hunters has discovered as many as six low-mass planets around two nearby Sun-like stars, including two “super-Earths” with masses 5 and 7.5 times the mass of Earth. The researchers, led by Steven Vogt of the University of California, Santa Cruz, and Paul Butler of the Carnegie Institution of Washington, said the two “super-Earths” are the first ones found around Sun-like stars.

Artist’s vision of a neutron star centered in a disk of hot plasma drawn from its red companion star. Physicists have theorized that an electroweak star might be the next step before total collapse of a neutron star into a black hole.

Dying, for stars, has just gotten more complicated.

Two Earth-sized Bodies With Oxygen Rich Atmospheres Found, But They’re Stars Not Planets

091112141309-large

Sloan Digital Sky Survey spectroscopy of this inconspicuous blue object.

Astrophysicists at the University of Warwick and Kiel University have discovered two earth sized bodies with oxygen rich atmospheres — however there is a bit of a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves, as they are not planets but are actually two unusual white dwarf stars.
