2012-01-01 • the GJ1214b, a sub-Neptune suspected of hosting an atmosphere, has been observed to have a flat transmission spectrum • It is reasonable to assume the presence of clouds in exoplanet atmospheres is a wide spread phenomena, therefore understanding and characterization of exoplanet atmospheres is linked to our understanding of the clouds "GJ1214b is quite close to Earth, just 42 light years away, and it orbits its star in just 1.6 days." That fast orbit gave scientists the opportunity to record the exoplanet's flat spectrum, ruling out an atmosphere of simple hydrogen, water, carbon dioxide or methane. This is an artistic depiction of the exoplanet GJ1214b. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. Its parent star is 42 light-years from the Sun, in the constellation Ophiuchus.

In this video, I describe my research on the super-Earth exoplanet GJ 1214b. 2015-11-02 2012-02-22 We observed the transiting super-Earth exoplanet GJ1214b using warm Spitzer at 4.5μm wavelength during a 20 day quasi-continuous sequence in 2011 May. The goals of our long observation were to accurately deﬁne the infrared transit radius of this nearby super-Earth, to search for the secondary eclipse, and to search for other 2014-01-01 Using data from the Hubble Space Telescope, researchers from the University of Chicago have detected clear evidence of clouds in the atmosphere of exoplanet GJ1214b.. Weather forecasters on exoplanet GJ1214b would have an easy job. Today’s forecast: cloudy.

2012-02-23 · It's difficult to blink without seeing a press release on an unusual exoplanet. This time it's GJ1214b who's back in the headlines. It was discovered by the Mearth project in 2009, using the transit method. Scientists are the first to simulate 3-D exotic clouds on an exoplanet 29 October 2015, by James Urton An artistic depiction of the exoplanet GJ1214b. The lack of absorption features in the transmission spectrum of exoplanet GJ1214b rules out a hydrogen-rich atmosphere for the planet. It is consistent with an atmosphere rich in water vapour or abundant in clouds.

Comparison of the size of Earth, exoplanet GJ1214b, and Neptune (License: CC-BY-SA, by Aldaron) The field of extra-solar planet research is still a young one, but progress over the last few years has been startling. We observed the transiting super-Earth exoplanet GJ1214b using warm Spitzer at 4.5μm wavelength during a 20 day quasi-continuous sequence in 2011 May. The goals of our long observation were to accurately deﬁne the infrared transit radius of this nearby super-Earth, to search for the secondary eclipse, and to search for other Clouds in the atmosphere of the super-Earth exoplanet GJ1214b Kreidberg, Laura Bean, Jacob L. Désert, Jean-Michel Benneke, Björn Deming, Drake Stevenson, Kevin B. Seager, Sara Berta-Thompson, Zachory Seifahrt, Andreas Homeier, Derek Astronomers using the Hubble Space Telescope have discovered a new class of alien planets, so-called steamy waterworlds.

The transmission spectrum of GJ1214b is striking: it is completely featureless at infrared wavelengths, with none of the patterns of spikes and dips that this sort of spectrum normally has. Much effort has been focused on using transmission spectroscopy to characterize the atmosphere of the super-Earth archetype GJ1214b (refs 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17), but previous observations did not have sufficient precision to distinguish between two interpretations for the atmosphere. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214.

GJ1214b is too hot for life, but it’s not too difficult for us to imagine that we could make similar observations of the atmosphere of a planet that was a little cooler in temperature than GJ1214b and could potentially host life. Microbial and plant life on Earth have dramatically altered our atmosphere over its history.

"GJ1214b is quite close to Earth, just 42 light years away, and it orbits its star in just 1.6 days." That fast orbit gave scientists the opportunity to record the exoplanet's flat spectrum, ruling out an atmosphere of simple hydrogen, water, carbon dioxide or methane.
