The astro-comb will try to 'rediscover' Venus by measuring its gravitational effects on th...

Astronomers looking for exoplanets are using a fine-toothed comb – a fine-toothed astro-comb, to be precise. And just to make sure it works, the first planet they’ll be looking for is Venus. Developed by astronomers Chih-Hao Li and David Phillips of the Harvard-Smithsonian Center for Astrophysics, the astro-comb uses a new spectroscopic device installed in the Italian Telescopio Nazionale Galileo in the Canary Islands that will detect the beclouded planet by its gravitational effect on the Sun as a test of a potentially valuable tool in the hunt for Earth-like planets beyond our Solar System.  Read More

In a display of interstellar teamwork, NASA’s Hubble, Spitzer and Kepler space telescopes have discovered clear skies and water vapor in the atmosphere of a Neptune-sized planet orbiting a star 120 light years from Earth. According to the space agency, this may not only provide insights into the formation of giant exoplanets, but also act as a new tool for detecting water on Earth-like planets orbiting other stars.  Read More

The new method will attempt to find traces of a tell-tale radio signal, known as an Io-con...

A new technique pioneered by a team of scientists from the University of Texas, Arlington, may hold the key to detecting moons orbiting distant exoplanets, a feat which is currently beyond the grasp of modern astronomy. Such a technique would afford scientists a greater opportunity of discovering a planetary body capable of sustaining life.  Read More

Scientists suggest looking for industrial pollution as a new way of searching for extrater...

According to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), we might soon be able to detect hints of technologically advanced alien civilizations by measuring high levels of polluting gases in the atmospheres of distant exoplanets. The approach should become viable soon after the James Webb Space Telescope (JWST) is launched in late 2018.  Read More

With the aid of NASA's Kepler spacecraft, a team of astronomers, including members from the Harvard-Smithsonian Center for Astrophysics, has discovered an exoplanet with the longest yearly cycle ever recorded. The planet, imaginatively named Kepler-421b, takes an impressive 704 days to orbit its parent, a dim type K star.  Read More

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

According to a survey conducted by astronomers at Cornell University, the Milky Way may be...

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

Kepler-10c is 17 times more massive than the Earth (Image: NASA/Harvard-Smithsonian Center...

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
