Astronomers using NASA’s Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star, a finding that may challenge current theories about planet formation. The suspected planet is orbiting the diminutive red dwarf TW Hydrae, a popular astronomy target located 176 light-years away from Earth in the constellation Hydra the Sea Serpent.

Thick smoke billows across the landscape in these digital photographs of the western United States. Both photographs were taken by astronauts aboard the International Space Station (ISS) on June 19, 2013.

This image taken by the Hubble Space Telescope’s Wide Field Camera 3 capturing Nebula NGC 6302, was released on June 18, 2013. With an estimated surface temperature of about 250,000 degrees C (450,032 F), Nebula NGC 6302 shines brightly in ultraviolet light but is hidden from direct view by a dense torus of dust.

Interacting galaxy duo Arp 142 captured by NASA Hubble Space Telescope, released on June 21, 2013. The pair contains the disturbed, star-forming spiral galaxy NGC 2936, along with its elliptical companion, NGC 2937 at lower left.

A full-circle view released by NASA on June 20, 2013, combined nearly 900 images taken by NASA’s Curiosity Mars rover, generating a panorama with 1.3 billion pixels in the full-resolution version. The view is centered toward the south, with north at both ends. It shows NASA’s Mars rover Curiosity at the ‘Rocknest’ site where the rover scooped up samples of windblown dust and sand.

A mosaic featuring the spectacular Kasei Valles on Mars, comprised of 67 images taken with the High Resolution Stereo Camera on the European Space Agency’s Mars Express, released on June 6, 2013. The mosaic spans 613 mi (987 km) north–south (19–36°N) and 983 mi. (1,550 km) east–west (280–310°E).

The underlying magnetic structure of the Sun and how it appears above its surface can be revealed by combining different solar images taken at almost the same time, on June 7, 2013.
