New Hubble Data Offer More Details About Cloudy Alien World
2013-12-31 11:53:25

A previously-discovered alien world that has an atmosphere that seems to be made up entirely of water vapor or some form of heavy molecule has now been discovered to be very cloudy.

Hubble Images Variable Star's Light Echo

Observations from the NASA/ESA Hubble Space Telescope, collected over the span of five weeks, show the variable star RS Puppis growing alternately brighter and dimmer – a phenomenon known as a light echo.

Hubble Finds Europa Water Vapor

NASA's "Behind the Webb" series of videos that follow the construction and testing as the James Webb Space Telescope is being pieced together.

Five Alien Worlds With Water Detected By Hubble Space Telescope
2013-12-03 14:19:52

Two teams of scientists have discovered faint signatures of water in the atmospheres of five exoplanets. This is the first study to conclusively measure and compare the profiles and intensities of these signatures on multiple worlds.

Endeavour launched from Kennedy Space Center on December 2, 1993 at 4:27 AM EST and landed at Kennedy on December 13 at 12:25 AM EST. The shuttle orbited 163 times at an altitude of 321 nautical miles at an inclination of 28.45 degrees and travelled 4.4 million miles. The mission lasted 10 days, 19 hours, 58 minutes, and 37 seconds. This was the first mission to repair and maintain the Hubble Space Telescope. It involved the second longest spacewalk to date at nearly 8 hours. The final...

Scott Altman is a test pilot and NASA astronaut. He was born Scott Douglas Altman on August 15, 1959 in Lincoln, Illinois. He grew up in Pekin, Illimois and graduated from Pekin Community High School in 1977. He continued on to the University of Illinois, where he earned a Bachelor of Science degree in aeronautical and astronautical engineering. He was commissioned in the United States Navy in August 1981 and received his Navy wings of gold in February 1983. Altman was deployed to the Western...

Adaptive Optics -- Adaptive optics is a technology to improve the performance of Earth-based telescopes, reversing the effect of atmospheric distortions. When light from a star or another astronomical object enters the Earth's atmosphere, the different temperature layers and different wind speeds distort and move the image in various ways (see seeing for a proper discussion). The net result is that an 8 meters or 10 meters telescope (like the VLT or Keck), while theoretically capable...

Hubble's Variable Nebula -- Hubble's variable nebula is named (like the Hubble telescope itself) after the American astronomer Edwin P. Hubble, who carried out some of the early studies of this object. It is a fan-shaped cloud of gas and dust which is illuminated by R Monocerotis (R Mon), the bright star at the bottom end of the nebula. Dense condensations of dust near the star cast shadows out into the nebula, and as they move the illumination changes, giving rise to the variations first...

Hourglass Nebula -- This is an image of MyCn18, a young planetary nebula located about 8,000 light-years away, taken with the Wide Field and Planetary Camera 2 (WFPC2) aboard NASA's Hubble Space Telescope (HST). This Hubble image reveals the true shape of MyCn18 to be an hourglass with an intricate pattern of "etchings" in its walls. This picture has been composed from three separate images taken in the light of ionized nitrogen (represented by red), hydrogen (green), and doubly-ionized...
