Although liquid water covers a majority of Earth's surface, scientists are still searching for planets outside of our solar system that contain water. Caltech researchers have used a new technique to analyze the atmospheres of such exoplanets, making the first detection of water in the atmosphere of the Jupiter-mass planet orbiting the nearby star tau Bo÷tis. This technique could help researchers learn about how many planets with water -- like Earth -- exist within our galaxy.

|The closest and brightest supernova in decades, SN 2014J, brightens faster than expected for Type Ia supernovae, the exploding stars used to measure cosmic distances, according to University of California Berkeley astronomers. Another recent supernova also brightened faster than expected, suggesting that there is unsuspected new physics going on inside these exploding stars. The finding may also help physicists improve their use of these supernovae to measure cosmic distance. ...> Full Article|

|A new study, MicroRNA Expression Profiles in Cultured Human Fibroblast in Space -- Micro-7 for short -- will examine the effect of gravity on DNA damage and repair. ...> Full Article|
|NASA is building new technologies to refuel and repair existing satellites in orbit. After concluding a successful ground-based test of robotic satellite refueling technology, NASA is preparing for a new round of demonstrations on the space station. The next Automated Transfer Vehicle, scheduled for launch to the space station in June, will deliver a new RRM task board and the Visual Inspection Poseable Invertebrate Robot to accomplish RRM objectives. ...> Full Article|
|A team of Australian and American astronomers have been studying nearby galaxy M83 and have found a new superpowered small black hole, named MQ1, the first object of its kind to be studied in this much detail. ...> Full Article|
|Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe. ...> Full Article|
|New images from the Smithsonian's Submillimeter Array telescope provide the most detailed view yet of stellar nurseries within the Snake nebula. These images offer new insights into how cosmic seeds can grow into massive stars. ...> Full Article|
|On Jan. 28, 2014, NASA's Interface Region Imaging Spectrograph, or IRIS, witnessed its strongest solar flare since it launched in the summer of 2013. Solar flares are bursts of X-rays and light that stream out into space, but scientists don't yet know the fine details of what sets them off. ...> Full Article|
|The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from the Niels Bohr Institute, among others, have detected a stream of stars in one of the Andromeda Galaxy's outer satellite galaxies, a dwarf galaxy called Andromeda II. The movement of the stars tells us that what we are observing is the remnant of a merger between two dwarf galaxies. Mergers between galaxies of such low mass has not been observed before. ...> Full Article|
|A new calibration of the Large Underground Xenon dark matter detector brought a 10-fold increase in calibration accuracy, confirming findings announced last October from the instrument's first 90-day run. If low-mass 'WIMP' particles had passed through the detector, Large Underground Xenon would have found them. ...> Full Article|

Scientists using the Australian Commonwealth Scientific and Industrial Research Organisation's Parkes telescope and another telescope in South Africa have found evidence that a tiny star called PSR J0738-4042 is being pounded by asteroids -- large lumps of rock from space.

|A giant sunspot -- a magnetically strong and complex region on the sun's surface -- has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation. ...> Full Article|
|Researchers at UCL have studied the behaviour of the Sun's coronal mass ejections, explaining for the first time the details of how these huge eruptions behave as they fall back onto the Sun's surface. In the process, they have discovered that coronal mass ejections have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of times larger. ...> Full Article||
