Hubble's stunning mosaic of the Andromeda galaxy comprises 411 individual images (Image: N...

NASA has released a stunning panoramic mosaic of our closest galactic neighbor, the Andromeda Galaxy. The image was captured by NASA's flagship Hubble Space Telescope, and features an impressive 100 million stars spanning 40,000 light years. The image is comprised of 1.5 billion pixels and represents Hubble's largest mosaic to date.  Read More

NASA's Dawn spacecraft is currently in the final stages of its historic mission to place a satellite in orbit around the dwarf planet Ceres. The primary mission will take 16 months and will see the robotic explorer capture detailed images and measurements of Ceres, greatly improving our knowledge of the solar system.  Read More

The Dawn spacecraft has lifted the veil on another corner of the Solar System by taking its best image yet of the dwarf planet Ceres. The nine-pixel-wide image was taken from a distance of 740,000 mi (1.2 million km) from Ceres as part of the final calibration of Dawn's science camera as the unmanned probe approaches the 590 mi (950 km) wide planetoid, which it will rendezvous with and orbit in March of next year.  Read More

With NASA'S New Horizons spacecraft scheduled to pass Pluto next year, the space agency has announced the discovery of three Kuiper Belt objects (KBO); one of which may be the unmanned probe’s next destination. Located in the constellation of Sagittarius, the primordial asteroids were found after a detailed survey using the Hubble Space Telescope.  Read More

In a display of interstellar teamwork, NASA’s Hubble, Spitzer and Kepler space telescopes have discovered clear skies and water vapor in the atmosphere of a Neptune-sized planet orbiting a star 120 light years from Earth. According to the space agency, this may not only provide insights into the formation of giant exoplanets, but also act as a new tool for detecting water on Earth-like planets orbiting other stars.  Read More

A star accompanying a rare type of supernova in close orbit has been discovered by astronomers using NASA's Hubble Space Telescope. Confirming a long-held theory that the explosion originated in a binary star arrangement, observations verify that the companion star precipitated the destruction of the aging primary star by drawing off mass until its core collapsed and triggered a supernova event.  Read More

The foreground galaxy can be seen cutting across the lensing light from the distant mergin...

An international team of astronomers has used a range of telescopes including the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a pair of galaxies colliding at a time when the universe was just half its current age. The project made use of a gravitational magnifying glass created by the gravity of a galaxy between Earth and the subject, and required observations in both visible and infrared light.  Read More

NASA’s Hubble and Spitzer telescopes have been used to examine a distant elliptical galaxy known as Sparky. The observations represent the first glimpse at the earliest stages of massive galaxy construction, shedding light on an area of frenzied star production in the early universe.  Read More

NASA has assembled a team of scientists and engineers to lay the first tentative plans for a successor platform to the Hubble and James Webb telescopes. The project, currently in the study phase, is being assessed for the technological and financial requirements needed to create so advanced a deep space observation platform.  Read More

As the US prepares for 4th of July fireworks here on Earth, a nearby spiral galaxy similar to our Milky Way is putting on a pyrotechnics display of its own. The galaxy, NGC 4258 (also known as Messier 106 or M 106), is ejecting gas and high-energy particles in a spectacular display of power that is rippling across the face of the galaxy with shock waves of stellar energy.  Read More
