Earth's strongest winds wouldn't even be a breeze on these planets
01-09-2007 · EurekAlert!New measurements for three planets outside our solar system indicate their temperatures remain fairly constant -- and blazing hot -- from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent darkness.

- Planet orbiting a giant red star discovered with hobby-eberly telescope
08-02-2007 · EurekAlert!
A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system. The new discovery is helping astronomers to understand what will happen to the planets in our solar system when our Sun becomes a red-giant star, expanding so much that its surface will reach as far as Earth's orbit.

- NASA scientists detect spectrum of planets orbiting other stars
02-22-2007 · EurekAlert!
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth.

- To curious aliens, Earth would stand out as living planet
12-21-2007 · EurekAlert!
With powerful instruments scouring the heavens, astronomers have found more than 240 planets in the past two decades, none likely to support Earth-like life.

- Tracking alien turbulences with Venus Express
04-03-2007 · European Space Agency (ESA)
New images and data from ESA's mission to Venus provide new insights into the turbulent and noxious atmosphere of Earth's sister planet. What causes violent winds and turbulences? Is the surface topography playing a role in the complex global dynamics of the atmosphere? Venus Express is on the case.

- First X-ray detection of a colliding-wind binary beyond the Milky Way
02-16-2007 · European Space Agency (ESA)
Imagine two stars with winds so powerful that they eject an Earth's worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce multimillion-degree gas, which radiates brilliantly in X-rays. Astronomers have conclusively identified the X-rays from about two-dozen of these systems in our Milky Way. But they have never seen one outside our galaxy — until now.

- 3.2 billion-year-old surprise: Earth had strong magnetic field
04-04-2007 · EurekAlert!
Geophysicists at the University of Rochester announce in today's issue of Nature that the Earth's magnetic field was nearly as strong 3.2 billion years ago as it is today.The findings, which are contrary to previous studies, suggest that even in its earliest stages the Earth was already well protected from the solar wind, which can strip away a planet’s atmosphere and bathe its surface in lethal radiation.

- Gliese 581: 1 planet might indeed be habitable
12-13-2007 · EurekAlert!
In April, a European team of astronomers announced in Astronomy & Astrophysics the discovery of two possibly habitable Earth-like planets. A&A is now publishing two independent, detailed studies of this system, which confirm that one of the planets might indeed be located within the habitable zone around the star Gliese 581.

- Double Star mission extended
11-16-2006 · European Space Agency (ESA)
Earlier this month, ESA's Science Programme Committee (SPC) unanimously approved a nine-month extension of ESA's involvement in the China/ESA Double Star mission. Double Star is currently studying the Earth's magnetosphere - the natural protective shield surrounding our planet - and its interaction with the solar wind.

- Aerosol pollution slows down winds and reduces rainfall
01-22-2007 · EurekAlert!
Near-surface winds provide a renewable source of clean energy and evaporate water, helping rain clouds to build up. But aerosolized particles created from vehicle exhaust and other contaminants can accumulate in the atmosphere and reduce the speed of winds closer to the Earth's surface, which results in less wind power available for wind-turbine electricity and also in reduced precipitation, according to a study by Stanford and NASA researchers.
