This is a composite image of the active galaxy M82 from infrared observations by Spitzer Space Telecope in three wavelength bands coded in red (longest wavelength), green, and blue (shortest wavelengths).
This is an artist's impression of how the very early universe (less than one billion years old) might have looked when it went through a voracious onset of star formation, converting primordial hydrogen into myriad stars at an unprecedented rate. The deepest views of the cosmos from the Hubble Space Telescope (HST) yield clues that the very first stars may have burst into the universe as brilliantly and spectacularly as a firework finale.
One of the world’s largest artificial lakes, Lake Nasser is named after the Egyptian President Gamal Abdul Nasser, who is largely responsible for the lake’s creation. President Nasser decided to build the Aswan High Dam across the Nile, forming a lake approximately 550 kilometers 340 miles long. In this astronaut photograph taken from the International Space Station, the water of Lake Nasser stands out from its surroundings due to sunglint.
This view combines frames taken by the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity on the rover's 652nd through 663rd Martian days, or sols (Nov. 23 to Dec. 5, 2005), at the edge of 'Erebus Crater.' The mosaic is presented as a polar projection. This type of projection provides a kind of overhead view of all of the surrounding terrain.
This projection of the Mars Exploration Rover provides a true-to-scale overhead view of the rover deck and nearby surrounding terrain. The view here shows outcrop rocks, sand dunes, and other features out to a distance of about 82 feet from the rover. Opportunity examined targets on the outcrop called 'Rimrock' in front of the rover, testing the mobility and operation of Opportunity's robotic arm in 2005.
Saturn's moon Enceladus is only 314 miles across, small enough to fit within the length of the United Kingdom, as illustrated here. The intriguing icy moon also could fit comfortably within the states of Arizona or Colorado.
Colors indicate infrared emission signatures in this mosaic of images from NASA's Mars Odyssey orbiter of a region of martian troughs named Nili Fossae. Analysis of this information from Odyssey's Thermal Emission Imaging System suggests that a deposit rich in the mineral olivine is about four times larger than indicated in earlier data from a lower-resolution infrared instrument on NASA's Mars Global Surveyor.
This photograph of the Sun, taken on December 19, 1973 during the third and final manned Skylab mission, shows one of the most spectacular solar flares ever recorded, spanning more than 365,000 miles across the solar surface. The flare gives the distinct impression of a twisted sheet of gas in the process of unwinding itself.
This mosaic of Mars is a compilation of images captured by the Viking Orbiter 1. The center of the scene shows the entire Valles Marineris canyon system, over 1,800 miles long and up to 5 miles deep, extending from Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east.
Hinode (Sunrise), formerly known as Solar-B before reaching orbit, was launched from the Uchinoura Space Center in Japan on September 23, 2006. Hinode was designed to probe into the Sun's magnetic field to better understand the origin of solar disturbances which interfere with satellite communications, electrical power transmission grids, and the safety of astronauts traveling beyond the Earth's magnetic field.

The French Parliament is considering a new bill that would allow university science classes to be taught in English. Politicians and academics across the spectrum are upset.
When two French ministers last month launched a new program to respond to the challenges of population aging, they gave it an English name: “Silver Economy.” But that didn’t strike a chord with their boss.
