Galaxy clusters, the rarest of galaxy groupings, can be difficult for astronomers to find. NASA‘s Wide-field Infrared Survey Explorer (WISE) space telescope, however, has just found a gigantic galaxy cluster, and is expected to uncover thousands more. The new findings …

Mars Rover Opportunity Completes Walkabout of Matijevic Hill

NASA announced today that Mars rover Opportunity has completed a reconnaissance circuit around an area named “Matijevic Hill.” Opportunity began its study of the location at the beginning of October. The site is named after Jacob Matijevic, who led the …

Mars Rover Curiosity Has Fully Analyzed Martian Soil

Mars Rover Curiosity has now used each of its on-board instruments to analyze Martian soil. Though researchers have found a complex chemistry in the soil on Mars, they haven’t found what would be considered a major discovery: carbon-based organic compounds …

Voyager Discovers New Region at the Edge of the Solar System
· 3

Excited NASA researchers today announced that the Voyager 1 spacecraft has encountered a new, unexpected region on its way out of the solar system. The scientists believe that the region is the final hurdle before Voyager enters interstellar space. The …

Study Shows Ice Loss at Both Poles Increasing

A new study by NASA and the European Space Agency (ESA) is showing that the melting rate for ice sheets in Greenland and Antarctica has increased over the past two decades. All together, the ice sheets are losing over three …

Hurricane Strength Forecasts Improved by NASA Study

A new NASA study shows that hurricane forecasters may soon be able to better predict hurricane and tropical storm strength by analyzing their relative-humidity levels. The study, published recently in the journal Geophysical Research Letters, looked at relative humidity data …

Mars Rover Curiosity Celebrates a Milestone
· 1

This week marks one year since Mars rover Curiosity launched on the Mars Science Laboratory from Cape Canaveral on Earth. Today, NASA provided a few statistics on the “new” rover to celebrate the occasion. Though Curiosity has only been on …

Astronomers Spot ‘Bridge’ of Hot Gas Connecting Galaxy Clusters

Astronomers using the Planck space telescope have confirmed the presence of a bridge of hot gas bridging the 10 million light-years of intergalactic space between two galaxy clusters. “Planck is helping to reveal hidden material between galaxy clusters that we …

Mars Rover Curiosity On the Move Again, With Rumors of a “Big” Discovery
· 4

After spending weeks stationed at the “Rocknest” site scooping up soil samples, Mars rover Curiosity this past week got the chance to once again drive across the surface of Mars. NASA announced today that over the weekend the rover first …

NASA Study Finds Global Sea Level Rising Once Again

Though the world’s oceans have been steadily rising at a rate of 3.2 mm per year for decades now, NASA scientists reported last year that the global sea level had actually dropped sharply between early 2010 and summer 2011, by …

NASA May Have Found A New Most Distant Galaxy
· 1

NASA today announced that astronomers have found a candidate for the new most distant galaxy ever seen. This comes just after a similar announcement in September, when a different red blob took the record. The object, dubbed MACS0647-JD, is observed …

Mars Rover Curiosity Measures Wind, Radiation Patterns on Mars

NASA announced today that, aside from scooping and analyzing Martian soil, Mars rover Curiosity’s measurements of wind and radiation patterns on Mars are helping researchers better understand the environment near the surface of Mars. Researchers with the Mars Science Laboratory …

Mars Rover Curiosity Chemically Analyzes Martian Soil

Mars rover Curiosity has placed the first solid sample of Martian soil into its Sample Analysis at Mars (SAM) instrument. The sample’s chemical makeup has been analyzed, looking specifically for compounds found in environments that can support life. The results …

NASA’s Mars Odyssey is Back Up and Running

NASA announced today that the Mars Odyssey orbiter has switched to a set of redundant equipment and has resumed its observational and relay duties. The equipment that was switched on, which included the orbiter’s backup main computer, had not been …

NASA Study Grades Climate Models, Finds Higher Temperatures Likely

NASA today announced the results of a new study by the National Center for Atmospheric Research. It shows that climate model projections that predict a greater rise in global temperature are more likely to be accurate than those predicting a …

Mars Rover Curiosity Team Switches to Earth Time
· 3

NASA announced today that the Mars rover Curiosity team will be switching back to Earth time. The team has spent the three months since Curiosity landed on Mars operating on Martian time. Mars has a day (called a “sol” by …

Mars Rover Curiosity Reveals Loss of Mars’ Atmosphere

NASA’s Mars rover Curiosity is now helping scientists understand how much of its original atmosphere the red planet may have lost. The data could help researchers predict whether Mars was ever habitable. Using its on-board Sample Analysis at Mars (SAM) …
