Along Came a Spider

A "stunning" closeup released this week shows part of the Tarantula Nebula, as seen by the Hubble Space Telescope.
The star-forming region of ionized hydrogen gas sits in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The cloud hosts many extreme cosmic phenomena, including supernova remnants, according to the European Space Agency.

Stormy Sun

The sun seems to come alive with arcing loops that show magnetic field lines interacting above its surface.
The extreme-ultraviolet image, taken in early March by the orbiting Solar Dynamics Observatory, captured "quite a dynamic display, and [is] further evidence that the sun is really coming out of its long solar minimum period of reduced activity," according to the observatory's website.

Rover on the Edge

The Mars rover Opportunity (noted with indicator arrow) peers over the southeastern rim of Mars's Santa Maria crater in a March 9 image by a camera on the orbiting High Resolution Imaging Science Experiment (HiRISE).
Opportunity has been studying the relatively fresh, 295-foot-wide (90-meter-wide) crater to better understand how it was formed and how weathering and erosion have changed the crater since the impact that caused the depression.

A crew from a Russian Soyuz capsule—including Oleg Skripochka (left), Alexander Kaleri (center), and Scott Kelly—rests minutes after they landed near the town of Arkalyk, Kazakhstan, on March 16.
The team completed nearly six months aboard the International Space Station.

Stars Are Born

Material ejected by newborn stars collides with surrounding gas and dust clouds to create a "surreal landscape" of glowing arcs, blobs, and streaks, according to the European Southern Observatory.
The image, captured by the observatory's Very Large Telescope in Chile and released March 16, offers a closeup view of the dramatic effects caused by baby stars in region NGC 6729—one of the stellar nurseries closest to Earth.

The eastern city of Torinoumi, Japan, is pictured on September 5, 2010, (left) and on March 12, a day after the magnitude 9 Japan earthquake and tsunami.
The German Optical RapidEye and TerraSAR-X satellites took the images, which are among more than 63 satellite observations made in the 48 hours following the disastrous earthquake, MSNBC reported.

Galaxies Far, Far Away

The oldest and most distant galaxy cluster (pictured in a composite satellite and x-ray image) has been discovered, the European Space Agency announced on March 9.
Unlike other structures observed in the early universe, galaxy cluster CL J1449 0856 is already in its prime, which is clear from the cluster's widely distributed x-ray emissions and evolved population of galaxies, according to the ESA's website.
