Spitzer Space Telescope sends cosmic Valentine rose
A cluster of newborn stars herald their birth in this interstellar Valentine's Day commemorative picture obtained with NASA's Spitzer Space Telescope. These bright young stars are found in a rosebud-shaped (and rose-colored) nebulosity known as NGC 7129. The star cluster and its associated nebula are located at a distance of 3300 light-years in the constellation Cepheus.

International interplanetary networking succeeds
A pioneering demonstration of communications between NASA's Mars Exploration Rover Spirit and the European Space Agency Mars Express orbiter succeeded. While Mars Express was flying over the area Spirit was examining, the orbiter transferred commands from Earth to the rover and relayed data from the robotic explorer back to Earth.

Gravitational lens reveals heart of a distant galaxy
Many examples are known where a galaxy acts as a gravitational lens, producing multiple images on the sky of a more distant object like a bright quasar hidden behind it. But there has been a persistent mystery for over 20 years: Einstein's general theory of relativity predicts there should be an odd number of images, yet almost all observed lenses have only 2 or 4 known images. Now, astronomers have identified a third, central image of a lensed quasar.
