Infrared Rose

This image from NASA's Spitzer Space Telescope shows young stars plus diffuse emission from dust. The Corona Australis region (containing, at its heart, the Coronet cluster) is one of the nearest and most active regions of ongoing star formation.

Galaxy NGC 1850

This ultraviolet image from NASA's Galaxy Evolution Explorer is of the large face on spiral galaxy NGC 3344. The inner spiral arms are wrapped so tightly that they are difficult to distinguish.

This artist's concept illustrates one possible answer to the puzzle of the 'giant galactic blobs.' NASA's Spitzer Space Telescope set its infrared eyes on one well-known blob located 11 billion light-years away.

At the Heart of Blobs (Artist Concept)

This artist's concept shows the smallest star known to host a planet. The planet, called VB 10b, was discovered using astrometry, a method in which the wobble induced by a planet on its star is measured precisely on the sky.

A Planet as Big as its Star

This artist's conception shows a binary-star, or two-star, system, called HD 113766, where astronomers suspect a rocky Earth-like planet is forming around one of the stars.
