This stunning shot of the giant star cluster Westerlund 2 was chosen as the official 25th ...

On this day 25 years ago, the Hubble Space Telescope launched aboard the Space Shuttle Discovery in what marked the beginning of an incredible journey, and the start of a new golden age in the exploration of our Universe. In celebration of this auspicious occasion, NASA has released the official image for Hubble's 25th anniversary in low-Earth orbit. The focus of the image is the Westerlund 2 cluster, which contains roughly 3,000 stars in the scope of its glittering expanse.  Read More

A team of ESO astronomers working from the La Silla Observatory, Chile, has detected the first direct reflection of light from an exoplanet orbiting a Sun-like star. The exoplanet, 51 Pegasi b, is what is known as a hot Jupiter, a prevalent form of gas giant that sits much closer to its parent star than our own Jovian neighbor.  Read More

A laser/telescope system may be able to de-orbit smaller pieces of orbital debris (Image: ...

Orbital debris is increasingly becoming a hazard to satellites and other spacecraft, which is why various groups have proposed concepts such as gas clouds, nets and sails for collecting it. While those approaches could capture larger objects, the problem of smaller pieces of debris – which whiz around the Earth like bullets – would remain. That's why an international group of scientists is developing a system that could shoot those bits down with a laser.  Read More

The Hubble Space Telescope, imaged in orbit by the crew of the Space Shuttle Atlantis in 2...

April 24 will mark a significant milestone in the life of one of mankind's greatest scientific instruments – the 25-year anniversary of the launch of the Hubble Space Telescope. This bus-sized piece of scientific equipment has become a household name, thanks to the incredible scientific insights and iconic images it has returned over the course of a quarter-century in low-Earth orbit. Join us as we celebrate the history and achievements of NASA's flagship space telescope.  Read More

Galaxy cluster Abell 3827 (Image: ESO)

New studies by astronomers are slowly throwing some light on dark matter, the invisible and mysterious stuff that scientists believe makes up much of the universe. For the first time, astronomers believe they've observed the interactions of dark matter via a factor other than the force of gravity.  Read More

The newly-discovered planet lies 13,000 light-years away, towards the center of the Milky ...

The NASA Spitzer Space Telescope has teamed up with the Polish Optical Gravitational Lensing Experiment (OGLE)'s Warsaw Telescope at the Las Campanas Observatory in Chile to observe a distant gas giant located some 13,000 light-years away. The discovery will help improve our understanding of the distribution of planets throughout the Milky Way galaxy.  Read More

Artist's impression of Chiron (Image: ESO)

A team of astronomers from MIT have detected signs of a possible ring system around the minor planet Chiron. First discovered in 1977, Chiron belongs to a class of minor planets known as centaurs. These bodies share some of the characteristics exhibited by both comets and asteroids, hence their classification as Centaurs, which in ancient mythology denoted a creature with the traits of both man and horse.  Read More

Hubble has been a boon to deep space exploration, gifting us iconic pictures of the skies and revealing new insights into the history of the early universe. For the next big step in space astronomy, NASA, ESA and the Canadian Space Agency are raising the stakes even higher with one of their most ambitious projects in decades: building the largest space telescope ever ... the James Webb Space Telescope.  Read More

The rare collision is seen here in this composite image from the Gemini, SMA and APEX  tel...

The European Southern Observatory's (ESO) Atacama Pathfinder Experiment telescope (APEX) has been used to solve a 340 year-old astronomical mystery. The findings reveal that an object that appeared in the sky in the 17th century was not a nova as astronomers at the time believed, but actually a rare stellar collision.  Read More

A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time.  Read More
