    The new telescope chip.

Credit: Australian National University =========================================================================================================================== Scientists have developed a new optical chip for a telescope that enables astronomers to have a clear view of alien planets that may support life. Seeing a planet outside the solar system which is close to its host sun, similar to Earth, is very difficult with today's standard astronomical instruments due to the brightness of the sun. Associate Professor Steve Madden from The Australian National University (ANU) said the new chip removes light from the host sun, allowing astronomers for the...

    The hunt for exoplanets has been heating up in recent years. Since it began its mission in 2009, over four thousand exoplanet candidates discovered by the Kepler mission, several hundred of which have been confirmed to be “Earth-like” (i.e. terrestrial). And of these, some 216 planets have been shown to be both terrestrial and located within their parent star’s habitable zone (aka. “Goldilocks zone”).

    CAPE CANAVERAL, Fla. – A white dwarf star in the Constellation Virgo turns out to be a "death star" worthy of "Star Wars." Astronomers announced Wednesday that they have discovered a rocky object coming apart in a death spiral around this distant star. They used NASA's exoplanet-hunting Kepler spacecraft to make the discovery, then followed up with ground observations. "This is something no human has seen before," said Andrew Vanderburg of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the lead author. "We're watching a solar system get destroyed," he said in a statement.

The four-planet system had been hiding out in the M-shaped, northern hemisphere constellation Cassiopeia, "just" 21 light years from Earth, a team reported in the journal Astronomy & Astrophysics. It comprises four planets—one giant and three super-Earths orbiting a star dubbed HD219134. Super-Earths have a mass higher than Earth's but are lighter than gas...

    Artist's impression showing a newly discovered Jupiter twin gas giant orbiting the solar twin star, HIP 11915. The planet is of a very similar mass to Jupiter and orbits at the same distance from its star as Jupiter does from the Sun. This, together with HIP 11915's Sun-like composition, hints at the possibility of the system of planets orbiting HIP 11915 bearing a resemblance to our own Solar System, with smaller rocky planets orbiting closer to the host star.

    Typically, exoplanets are observed indirectly using such techniques as the transit method, or by measuring changes in the radial velocity of host stars. In the vast majority of cases, astronomers aren’t able to detect the light from these planets due to their extreme distance from observational equipment. But VHS J1256b—a gas giant located 40 light-years from Earth—is close enough, bright enough, and distant enough from its host star to be seen and distinguished by our telescopes. The direct image of VHS J1256b, along with its spectral signature, was acquired by scientists at the Institute of Astrophysics of the Canaries (IAC),...

    The Australian discovery of a strange exoplanet orbiting a small cool star 500 light years away is challenging ideas about how planets form. "We have found a small star, with a giant planet the size of Jupiter, orbiting very closely," said researcher George Zhou from the Research School of Astrophysics and Astronomy. "It must have formed further out and migrated in, but our theories can't explain how this happened." In the past two decades more than 1,800 extrasolar planets (or exoplanets) have been discovered outside our solar system orbiting around other stars. The host star of the latest exoplanet, HATS-6,...

    The hunt for Earth-like planets around distant stars could soon become a lot easier thanks to a technique developed by researchers in Germany. In a paper published today, 18 February, in the New Journal of Physics, the team of researchers have successfully demonstrated how a solar telescope can be combined with a piece of technology that has already taken the physics world by storm—the laser frequency comb (LFC). It is expected the technique will allow a spectral analysis of distant stars with unprecedented accuracy, as well as advance research in other areas of astrophysics, such as detailed observations of the...

    NASA's Kepler space telescope is discovering alien planets again. The prolific spacecraft has spotted its first new alien planet since being hobbled by a malfunction in May 2013, researchers announced Dec. 18. The newly discovered world, called HIP 116454b, is a "super Earth" about 2.5 times larger than our home planet. It lies 180 light-years from Earth, in the constellation Pisces — close enough to be studied by other instruments, scientists said. "Like a phoenix rising from the ashes, Kepler has been reborn and is continuing to make discoveries," study lead author Andrew Vanderburg, of the Harvard-Smithsonian Center for Astrophysics...

    1. The Earthiest Kepler-78b is most similar to Earth in mass, diameter and composition; it could be made of rock with an iron core. But it’s no Earth analog, whizzing around its star in 8.5 hours, with temperatures exceeding 2,000° Celsius (SN Online: 10/30/13). 2. The wettest HR 8799c’s atmosphere lacks methane, which could signal life, but does have water and carbon monoxide (SN: 4/6/13, p. 5). Water has also been found in the atmospheres of WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b. 3. The rogue Planetary candidate PSO J318.5-22 has no parent star.

    You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again. A new mission concept, dubbed K2, would continue Kepler's search for other worlds, and introduce new opportunities to observe star clusters, young and old stars, active galaxies and supernovae. In May, the Kepler spacecraft lost the second of four gyroscope-like reaction wheels, which are used to precisely point the spacecraft, ending new data collection for the original mission. The spacecraft required three functioning wheels to maintain the precision pointing necessary to detect the signal of...
