More than 100 tiny satellites are set to launch into space on April 14th, in a demonstration of a possible future inexpensive technology that could pave the way for the $1,000 satellite. Clara Moskowitz reports
After prolonged periods in microgravity, astronauts' hearts became more spherical, according to scans done on the International Space Station. Sophie Bushwick reports
The asteroidlike object Chariklo orbits between Saturn and Uranus and has been found to have its own set of rings. Clara Moskowitz reports
An exhaustive search by NASA's Wide-Field Infrared Survey Explorer has found no hints of a theorized planet or dwarf star in our neck of the cosmic woods. Clara Moskowitz reports
The half-the-speed-of-light spin of a giant black hole suggests it grew by digesting another black hole in a galaxy merger. Clara Moskowitz reports
Spanish astronomers spotted a meteoroid impact at 61,000 kilometers per hour using a telescope network that automatically scans the moon. Clara Moskowitz reports
The Hubble Telescope's new set of Frontier Fields images includes a galaxy some 13-billion light-years away, which makes it a candidate for the most distant object ever seen. Clara Moskowitz reports
Galileo—who, among many accomplishments, was first to use a telescope to discover moons around Jupiter—was born 450 years ago this week. Clara Moskowitz reports
Exoplanet Kepler 413 b's tilt can vary by as much as 30 degrees over 11 years, leading to extremely erratic seasons. Clara Moskowitz reports
Astronomers have come up with a shopping list of what a planet needs to support life, perhaps even better than our Earth does, making them "superhabitable." Michael Moyer reports
On January 20th the European Space Agency woke its Rosetta probe after two-and-a-half years in hibernation, in preparation for its final approach to a comet
More than 3,000 astronomers assembled last week for the 223rd meeting of the American Astronomical Society. Clara Moskowitz reports
Two recently found supernovae are much farther away and brighter than almost any star explosion ever seen, perhaps because they wound up as rapidly spinning magnetars. Clara Moskowitz reports
The Wide-Field Infrared Survey Explorer satellite that went into hibernation in 2011 has been brought to life as an asteroid lookout. Clara Moskowitz reports
Ten-year-old Nathan Gray of Nova Scotia officially becomes the youngest person ever to identify a new supernova. Clara Moskowitz reports
Don't miss viewing Comet ISON, visible in the east before dawn, with a tail now as long as the bowl of the Big Dipper. Clara Moskowitz reports
India aims to become the fourth entity to send a mission to Mars with its launch of the Mars Orbiter Mission, aka Mangalyaan. Clara Moskowitz reports.
At a symposium on the danger of asteroid impacts, Apollo astronaut Rusty Schweickart said it's time for the planet to develop a strategy should a big rock come our way. Clara Moskowitz reports.
Two of the three known planets around the star Kepler 56 orbit their host out of line with the star's equator. Clara Moskowitz reports.
Voyager 1's own record of the plasma vibrations in its vicinity conclusively show that it has reached the space between the stars. John Matson reports
The distributed computing project Einstein@Home uses home computers to search through years of telescope data to find pulsars. John Matson reports.
NASA's WISE satellite surveyed the universe before being mothballed in 2011. Now it's being resurrected as a near-Earth asteroid scanner.
Although the Kepler space telescope's stabilization system is beyond repair, it has produced reams of data that have yet to be fully searched for exoplanets. John Matson reports.
The only issue related to the flip of the sun's magnetic field is that it corresponds with the peak of the sunspot cycle, when the sun is prone to launch flares and bursts of plasma into space that can effect satellites and power grids. John Matson reports.
Since it landed on Mars on August 6, 2012, the Curiosity rover has done photography, geology and roamed a good kilometer. John Matson reports
A huge cloud of plasma south of our galactic black hole could be evidence of a past feeding frenzy. John Matson reports
Theory said that muon neutrinos could transform into electron neutrinos. A neutrino detector confirms this by catching many more electron neutrinos than it should have otherwise. John Matson reports
The black hole in galaxy NGC 1277 is way more massive than usual. Astronomers hypothesize it was ejected from another galaxy before settling in its new home. John Matson reports
The star WX UMa went from 5,000 degrees Fahrenheit to 30,000 degrees F in less than three minutes. Chris Crockett reports
A reaction between two common molecules occurs much faster at frosty interstellar temperatures than on our toasty Earth due to a cold-stabilized transition and quantum tunneling. John Matson reports
