Exoplanet

Astronomers have disproved the existence of two exoplanets thought to orbit Gliese 581 in ...

Those packing their bags for a trip to the two potentially habitable exoplanets previously claimed to be orbiting the red dwarf star Gliese 581 had better rethink their travel plans. Astronomers at Pennsylvania State University say the planets, Gliese 581 d and Gliese 581 g, don't actually exist.  Read More

A survey conducted by astronomers at Cornell University has taken into account the characteristics of 637 known exoplanets and elaborated a Biological Complexity Index (BCI) to assess the relative probability of finding complex life on them. Their data supports the view that as many as one hundred million planets scattered around the Milky Way, and perhaps more, could support life beyond the microbial stage.  Read More

The Hubble Space Telescope has taken a long-exposure picture of space in the ultraviolet, ...

A newly-released picture taken by the Hubble Telescope is adding more color to the Hubble Ultra Deep Field (HUDF) image by detecting thousands of galaxies in the ultraviolet spectrum. The study, called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF), directly imaged stars and other celestial bodies that would have been impossible to observe on the ground, and gives astronomers critical information that will prove useful as the launch of the more powerful James Webb Space Telescope approaches.  Read More

This infrared image, one of the first taken by SPHERE, displays a dust ring orbiting a nea...

A new scientific instrument for detecting and observing remote exoplanets has been successfully installed on Unit 3 of the ESO's Very Large Telescope (VLT). The Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, or SPHERE, recently returned its first set of images and is promised to revolutionize the exploration and study of these distant celestial bodies.  Read More

Despite being currently offline, the Kepler space telescope is still turning up surprises. One of them is an Earth-like planet that’s so large that astronomers at the Harvard-Smithsonian Center for Astrophysics call it a “mega-Earth.” Planet Kepler-10c is 17 times heavier than the Earth, and may require scientists to rethink their ideas on planet formation and the likelihood of life in our galaxy.  Read More

Data collected from observations recorded by NASA's Cassini mission has been used to propose ways to better understand the atmospheres of exoplanets. By studying the light of sunsets on Saturn’s satellite, Titan, scientists have shown how spectra are subtly altered when passing through a hazy atmosphere, thereby giving a greater insight into interpreting the spectral readings of the atmosphere of these distant worlds.  Read More

The giant exoplanet GU Psc b has an orbital period of 80,000 years (Image: Lucas Granito/G...

Using an infrared camera, astronomers at the University of Montreal have discovered and directly imaged GU Psc b, a planet with a mass 10 times greater than Jupiter's and orbiting its star at 2,000 times the distance between Earth and our sun. This very rare find will encourage scientists to start looking for exoplanets in places where, thus far, they hadn't even thought to look.  Read More

Artist's impressionof Beta Pictoris b

According to NASA, 1,703 planets orbiting 1,033 stars have been found so far, but very little is known about these planets beyond some deductions based on their orbits. That veil is lifting though, as demonstrated by Dutch astronomers who have for the first time measured the length of an exoplanet’s day. Using the European Southern Observatory’s Very Large Telescope (VLT) in Chile’s Atacama desert, the team has learned that the young extrasolar gas giant Beta Pictoris b has an eight-hour day and spins faster than any planet in the Solar System.  Read More

Artist's impression of Kepler-186f (Image: NASA)

The search for extraterrestrial life zeroed in a bit today as NASA announced that its unmanned Kepler Space Telescope detected the most Earth-like planet yet found beyond the Solar System. Named Kepler-186f, the new planet orbits a red dwarf star about 500 light years away from Earth in the constellation of Cygnus, is only 10 percent larger than our planet, and could have liquid water, which is essential for life as we know it.  Read More

Starshade and its space telescope (Image: NASA)

Apparently NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, thinks that what space exploration in the 21st century needs is spacecraft that are a bit more botanical. The center has released a video showing off its starshade spacecraft that opens up like a blossom. Bearing a resemblance to a cosmic sunflower, it’s designed to help astronomers to directly study exoplanets, including taking the first actual pictures of planets beyond our Solar System.  Read More
