For the first time, telescopes have captured the light spectra emitted directly from planets outside of our solar system. Researchers trained the infrared-sensitive Spitzer Space Telescope on two ...

In a first-ever discovery, astronomers have detected fierce, supersonic winds on a planet outside of our own Solar System, what is called an extrasolar planet, or exoplanet. In this case, winds of up ...

ABSTRACT We have used high‐resolution optical spectra to search for obvious absorption or emission lines from the planets orbiting HD 209458 and 51 Pegasi. For each star, two spectra were obtained ...

The light from the planet was detected in infrared form by the Spitzer Space Telescope, which also detected the first light from another exoplanet, the gas giant HD 209458 b. Spitzer was launched in ...

The Weather Patterns of HD 209458b: If any of our loyal fans are like me (and most other sane people), winter is the worst time of year. Besides being cooped up inside the house for several months, ...

Exoplanet HD 209458b transits its star. The illuminated crescent and its colours have been exaggerated to illustrate the light spectra that the astronomers used to identify the six molecules in its ...

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or ...

After a few false starts, astronomers say they have finally observed water vapor in the atmosphere of a so-called hot Jupiter, a large gaseous planet tightly orbiting a distant star. Using NASA's ...

How about a planet that acts like a comet! The Hubble Space Telescope has found planet HD 209458b. NASA says it is a gas giant that is so close to its star'”about 4 million miles away'”that its ...
