Latest Exoplanetology Stories
SPHERE — the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument — has been installed on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile and has achieved first light.
Using new data from the HARPS spectrometer at the ESO’s La Silla observatory in Chile, an international team of scientists have discovered two exoplanets orbiting a nearby ancient star.
Two worlds orbiting a distant star are about to become a snack of cosmic proportions. Astronomers announced on Monday that the planets Kepler-56b and Kepler-56c will be swallowed by their star in a short time by astronomical standards. Their ends will come in 130 million and 155 million years, respectively.
The planets of our solar system come in two basic flavors, like vanilla and chocolate ice cream.
Astronomers announced on Monday that they have discovered a new type of planet - a rocky world weighing 17 times as much as Earth.
Life in the universe might be even rarer than we thought.
By studying a hazy sunset on Titan via the Cassini spacecraft, scientists are learning new ways to better understand the atmospheres of exoplanets orbiting distant stars.
Believed to be retired for good after breaking down last year, the Kepler spacecraft has been revived and will be part of a newly-approved NASA mission to seek out new exoplanets while also expanding its role into the realm of astrophysical observations.
Using observations from multiple observation facilities, an international team of astronomers has identified a very unusual planet that takes around 80,000 Earth years to orbit its sun.
Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours.
Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...
Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...
