Hubble Spots Pitch Black Hot Jupiter that “Eats Light” The study of extra-solar planets has revealed discoveries that have confounded expectations and boggled the mind! Whether it’s Super-Earths that become diamond planets, multiple rocky planets orbiting closely together, or “Hot Jupiters” with traces of gaseous metal in their atmospheres, there’s been no shortage of planets out there for which there is no comparison here in the Solar System. In this respect, WASP-12b is in good company. This Hot-Jupiter, located in a star system 1400 light years from Earth in the direction of the Auriga constellation, was recently studied by a team of astronomers using theRead More →

Loss of Signal: Cassini Spacecraft Plunges Into Saturn Until the very end, Cassini displayed just how robust and enduring this spacecraft has been throughout its entire 20 years in space and its 13-year mission at Saturn. As Cassini plummeted through the ringed-planet’s atmosphere, its thrusters fought the good fight to keep the antenna pointed at Earth for as long as possible, sending as much of the last drops of science data as it could. Cassini endured about 40 seconds longer than expected before loss of signal was called at 11:55:46 UTC “I hope you’re all deeply proud as this accomplishment,” said Cassini Project Manager EarlRead More →

Fifty years after Jocelyn Bell discovered the first pulsar, students are no longer going through reams of paper from pen chart recorders but instead search through 1,000s of terabytes of data to find these enigmatic pulsating radio stars. The most extreme binary pulsar system so far, with accelerations of up to 70 g has been discovered by researchers at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn. At their closest approach the orbit of the pulsar and its companion neutron star would easily fit inside the radius of the Sun. Powered by WPeMaticoRead More →

Astronomers Spot Hellish World with Titanium in its Atmosphere The hunt for exoplanets has turned up many fascinating case studies. For example, surveys have turned up many “Hot Jupiters”, gas giants that are similar in size to Jupiter but orbit very close to their suns. This particular type of exoplanet has been a source of interest to astronomers, mainly because their existence challenges conventional thinking about where gas giants can exist in a star system. Hence why an international team led by researchers from the European Southern Observatory (ESO) used the Very Large Telescope (VLT) to get a better look at WASP-19b, a Hot JupiterRead More →

Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b’s atmosphere. The results are also in stark contrast to observations of another similarly sized exoplanet. Powered by WPeMaticoRead More →

Cassini: The Mission That Will Live Forever “With Cassini, we had a rare opportunity and we seized it,” said Linda Spilker, Cassini Mission Scientist. And on Friday, September 15, we say goodbye to this incredible spacecraft. Since 2004, Cassini has been orbiting Saturn, exploring the magnificent gas giant planet while weaving through an incredibly diverse assortment of 60-plus icy moons, and skimming along the edges of the complex but iconic icy rings.

Three scientists at Niels Bohr Institute (NBI), University of Copenhagen, have carried out extensive computer simulations related to star formation. They conclude that the present idealized models are lacking when it comes to describing details in the star formation process. “Hopefully our results can also help shed more light on planet formation,” says Michael Küffmeier, astrophysicist and head of the research team.

Astronomers from the University of Geneva (UNIGE), Switzerland and collaborators used the Hubble Space Telescope to study an exoplanet that had been observed losing its atmosphere, forming an enormous cloud of hydrogen and giving the planet the appearance of a giant comet. During earlier observations in 2015, it was not possible to observe the whole cloud, whose shape was predicted by numerical simulations. Thanks to these new observations, however, the scientists have finally been able to confirm the initial predictions. The results are unveiled in the journal Astronomy & Astrophysics.

Russian-American Trio Blasts Off and Boards International Space Station After Fast Track Trajectory The Soyuz MS-06 rocket blasts off with the Expedition 53-54 crew towards the International Space Station from the Baikonur Cosmodrome in Kazakhstan, Tuesday, Sept. 12, 2017 (Wednesday, Sept. 13, Kazakh time). Credit: NASA/Bill Ingalls Barely a week and a half after the thrilling conclusion to the record breaking space endurance mission by NASA astronaut Peggy Whitson, a new Russian-American trio blasted off for the International Space Station (ISS) on a Russian Soyuz capsule and boarded safely early this morning Wednesday, Sept 13. after arriving as planned on a fast track orbital trajectory.Read More →

Three Possible Super-Earths Discovered Around Nearby Sun-Like Star Since it was launched in 2009, NASA’s Kepler mission has continued to make important exoplanet discoveries. Even after the failure of two reaction wheels, the space observatory has found new life in the form of its K2 mission. All told, this space observatory has detected 5,017 candidates and confirmed the existence of 2,494 exoplanets using the Transit Method during its past eight years in service. The most recent discovery was made by an international team of astronomers around Gliese 9827 (GJ 9827), a late K-type dwarf star located about 100 light-years from Earth.

The accelerating expansion of the Universe may not be real, but could just be an apparent effect, according to new research published in the journal Monthly Notices of the Royal Astronomical Society. The new study—by a group at the University of Canterbury in Christchurch, New Zealand—finds the fit of Type Ia supernovae to a model universe with no dark energy to be very slightly better than the fit to the standard dark energy model.

Inferno World with Titanium Skies Astronomers using ESO’s Very Large Telescope have detected titanium oxide in an exoplanet atmosphere for the first time. This discovery around the hot-Jupiter planet WASP-19b exploited the power of the FORS2 instrument. It provides unique information about the chemical composition and the temperature and pressure structure of the atmosphere of this unusual and very hot world. The results appear today in the journal Nature. ESO News Feed Go to Source Powered by WPeMaticoRead More →

A team of astronomers led by Elyar Sedaghati, an ESO fellow and recent graduate of TU Berlin, has examined the atmosphere of the exoplanet [WASP-19b] in greater detail than ever before. This remarkable planet has about the same mass as Jupiter, but is so close to its parent star that it completes an orbit in just 19 hours and its atmosphere is estimated to have a temperature of about 2000 degrees Celsius.

This Weekend: The Moon Photobombs ‘Planet-palooza’ at Dawn The planetary lineup at dawn (minus the Moon) from September 12th. Image credit and copyright: Alan Dyer (AmazingSky.com). Following the Moon and wondering where are the fleeting inner solar system planets are this month? While Jupiter and Saturn sink into the dusk on the far side of the Sun this month, the real action transpires in the dawn sky in mid-September, with a complex set of early morning conjunctions, groupings and occultations. First, let’s set the stage for the planetary drama. Mercury just passed greatest elongation 18 degrees west of the Sun on September 12th. The actionRead More →
