Kepler exoplanet tally passes 1,000

By - January 10, 2015 2 Pictures
NASA's Kepler space telescope's count of exoplanets has passed the magic 1,000 mark, including eight new "habitable" planets and 544 candidate planets. Having confirmed so many exoplanets and their characteristics provides a database large enough to allow astronomers to carry out statistical analysis and make very rough predictions about how many planets there are in our galaxy, as well as the odds of finding another Earth.

Kepler finds new exoplanet as it starts new mission

By - December 19, 2014 1 Picture
NASA's Kepler space telescope shows that it still has life in it as its extended mission begins to bear fruit. This week, the space agency announced that the spacecraft detected a new exoplanet, demonstrating that its K2 life extension mission is working. The planet, called, HIP 116454b, is 2.5 times larger in diameter than the Earth and orbits a star 180 light years from Earth in the constellation of Pisces every nine days at a distance that makes it much too hot for it to sustain life.

Detection of super-Earth transit puts ground-based telescopes in the hunt

By - December 2, 2014 1 Picture
When you're hunting for exoplanets many light years away, the complications posed by the Earth's atmosphere can make the search incredibly difficult for ground-based telescopes. That's why space-based telescopes, such as Hubble, Spitzer and Kepler, are generally employed for the job. But now for the first time, astronomers have detected the transit of a super-Earth in front of a nearby Sun-like star, which could see ground-based telescopes more widely used in categorizing the growing number of exoplanets expected to be discovered in the next few years.

Yale astronomers find exoplanet that simply can't keep time

By - October 31, 2014 1 Picture
Yale astronomers have discovered a low-mass, low-density exoplanet orbiting a distant star whose orbit boasts some fascinating and extreme characteristics. The yearly period of the exoplanet, known as PH3c, varies enormously from one orbit to another, and so eclectic are these orbits that it was undetectable by conventional exoplanet hunting techniques that rely on a periodic dip in the light of the parent star.

Astronomers use astro-comb to seek Earth-like exoplanets

By - October 19, 2014 2 Pictures
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.

NASA finds clear skies on exoplanet

By - September 27, 2014 6 Pictures
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.

Detecting industrial pollution could be an effective approach to finding ET

By - July 31, 2014 1 Picture
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
