As the solar wind encounters Mercury, it slows down, piles up and flows around the planet (gray ball). This figure shows the density of protons from the solar wind, as calculated by modeling of the planet's magnetic sheath, or magnetosphere. The highest density, indicated by red, is on the side facing the sun; yellow indicates [...]
NIST’s unique "sliding spark source" (inside the glass tubing) feeds ultraviolet light into NASA’s Solar Ultraviolet Magnetograph Investigation instrument, designed to measure magnetic fields on the sun. Credit: Reader/NIST With a brilliant, finely tuned spark of ultraviolet (UV) light, a physicist at the National Institute of Standards and Technology helped NASA scientists successfully position a [...]
The red giant carbon star CW Leonis as seen by the PACS and SPIRE cameras on board Herschel. The star itself is too bright to be seen well, but it is releasing material in a violent stellar wind, some of which is seen in a “bow shock” to the left of the star in this [...]
Keck II image of the young extrasolar planet HR 8799 b, seen as the point source in center of image. The bright light from the parent star HR 8799 is seen in background in yellow/red and has been removed in an annular region centered on the planet.

This visible full-disk image of the Earth was captured by GOES-15 on August 27, 2010 at 1800 UTC (2 p.m. EDT). At that time Hurricane Danielle, Tropical Storm Earl and a tropical wave were occurring in the Atlantic Ocean basin. (Credit: NOAA/CIRA) ScienceDaily (Sep. 1, 2010) — NASA and NOAA's latest Geostationary Operational Environmental Satellite, [...]
A NASA astronaut on the Space Shuttle Endeavor brought space back down to Earth. Astronaut Don Pettit took over 85 time-lapsed videos of Earth from his stint on the International Space Station to highlight features of the changing planet. "There is phenomenology that happens on a timescale that you can't see in real time," [...]
Edward Cheung, long-time principal engineer for the Hubble Space Telescope Development Project was recently dubbed Knight of the Royal Order of the Netherlands Lion. In this picture, the Governor of Aruba, Fredis Refunjol, fastens the royal decoration to Cheung’s jacket.

This illustration shows a CME blasting off the Sun’s surface in the direction of Earth. This left portion is composed of an EIT 304 image superimposed on a LASCO C2 coronagraph. Two to four days later, the CME cloud is shown striking and beginning to be mostly deflected around the Earth’s magnetosphere. The blue paths [...]
ScienceDaily (Sep. 1, 2010) — A new method of predicting solar storms that could help to avoid widespread power and communications blackouts costing billions of pounds has been launched by researchers at the University of Bradford. Solar storms involve the release of huge amounts of hot gas and magnetic forces from the surface of the [...]
The superwind galaxy NGC 4666. (Credit: ESO/J. Dietrich) ScienceDaily (Sep. 1, 2010) — The galaxy NGC 4666 takes pride of place at the centre of this new image, made in visible light with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. NGC 4666 is a remarkable galaxy [...]
