Telescopes are very simple devices in theory, but getting one to work in space means a complex assembly of mechanical parts that is expensive, difficult to build, and hard to operate in the hostile environment outside the Earth’s atmosphere. To simplify things, NASA aerospace engineer Jason Budinoff is working on the first space telescope made entirely from 3D-printed parts.  Read More

Scientists suggest looking for industrial pollution as a new way of searching for extrater...

According to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), we might soon be able to detect hints of technologically advanced alien civilizations by measuring high levels of polluting gases in the atmospheres of distant exoplanets. The approach should become viable soon after the James Webb Space Telescope (JWST) is launched in late 2018.  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

Once you've sent the first space probe to Pluto, what do you do for an encore? As NASA’s New Horizons spacecraft races to its encounter with the dwarf planet next year, the Hubble Space Telescope Time Allocation Committee have given its recommendation that the Hubble be used to find the Horizons’ next destination in the outer reaches of the Solar System.  Read More

The Hubble Space Telescope has taken a long-exposure picture of space in the ultraviolet, ...

A newly-released picture taken by the Hubble Telescope is adding more color to the Hubble Ultra Deep Field (HUDF) image by detecting thousands of galaxies in the ultraviolet spectrum. The study, called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF), directly imaged stars and other celestial bodies that would have been impossible to observe on the ground, and gives astronomers critical information that will prove useful as the launch of the more powerful James Webb Space Telescope approaches.  Read More

Kepler-10c is 17 times more massive than the Earth (Image: NASA/Harvard-Smithsonian Center...

Despite being currently offline, the Kepler space telescope is still turning up surprises. One of them is an Earth-like planet that’s so large that astronomers at the Harvard-Smithsonian Center for Astrophysics call it a “mega-Earth.” Planet Kepler-10c is 17 times heavier than the Earth, and may require scientists to rethink their ideas on planet formation and the likelihood of life in our galaxy.  Read More

Jupiter's Great Red Spot has been a source of inspiration and curiosity for generations of...

Data collected by NASA's Hubble Space Telescope over the past 20 years show Jupiter's Great Red Spot has been shrinking at an increasing rate to its current, and smallest, recorded size. The reduction is possibly due to the existence of eddies, that have been observed feeding into the planet-sized storm.  Read More

Recent data captured by NASA's Chandra Observatory and Spitzer Space Telescope has cast doubt on the basic model that accounts for the creation of star clusters. The data, collected from studies of NGC 2024, located in the Flame Nebula and the Orion Nebula Cluster, will require scientists to think up an entirely new approach as to how these celestial bodies come into creation.  Read More

WISE J085510.83-071442.5.0 is the coldest brown dwarf yet found (Image: NASA)

We tend to think of stars as being very, very hot, but what about a star that you could use as a deep freeze? Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered a dim star-like object with the catchy title WISE J085510.83-071442.5.0 that is colder than the North Pole. Lying about 7.2 light years from Earth, it is not only the coldest brown dwarf on record, but the fourth-closest star system to the Solar System.  Read More
