Steep Slopes On Mars Reveal Structure Of Buried Ice

A cross-section of a thick sheet of underground ice is exposed at the steep slope (or scarp) that appears bright blue in this enhanced-color view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. The view covers an area about 550 yards (500 meters) wide. Image Credit: NASA/JPL-Caltech/UA/USGS

January 11, 2018 – Researchers using NASA’s Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars’ surface are exposed in faces of eroding slopes. These eight scarps, with slopes as steep as 55 degrees, reveal new information about the internal layered structure of previously detected underground ice sheets in Mars’ middle latitudes.

Researchers Catch Supermassive Black Hole Burping … Twice

January 11, 2018 – A team led by CU Boulder researchers has caught a supermassive black hole in a distant galaxy snacking on gas and then “burping”—not once, but twice. CU Boulder Assistant Professor Julie Comerford, who led the study, said the supermassive black hole under study appears to have belched—essentially blasting out jets of bright light from the gas it inhaled—two times over the course of about 100,000 years. While astronomers have predicted such objects can flicker on and off as a result of gas feeding events, this is one of the few times one has been caught in the act. Read More


Citizen Scientists Discover Five-Planet System

Artist’s visualization of the K2-138 system, the first multi-planet system discovered by citizen scientists. The central star is slightly smaller and cooler than our sun. The five known planets are all between the size of Earth and Neptune; planet b may potentially be rocky, but planets c, d, e, and f likely contain large amounts of ice and gas. All five planets have orbital periods shorter than 13 days and are all incredibly hot, ranging from 800 to 1800 degrees Fahrenheit. Image Credit: NASA/JPL-Caltech/R. Hurt (IPAC)

January 11, 2018 – In its search for exoplanets—planets outside of our solar system—NASA’s Kepler telescope trails behind Earth, measuring the brightness of stars that may potentially host planets. The instrument identifies potential planets around other stars by looking for dips in the brightness of the stars that occur when planets cross in front of, or transit, them. Typically, computer programs flag the stars with these brightness dips, then astronomers look at each one and decide whether or not they truly could host a planet candidate. Read More


Sealed Up, Ready To Go: U.S. Air Force’s SBIRS GEO Flight-4 Missile Warning Satellite Encapsulated For Launch

January 11, 2018 – The U.S. Air Force’s fourth Space Based Infrared System (SBIRS) Geosynchronous Earth Orbit (GEO) satellite built by Lockheed Martin was encapsulated on January 9. The SBIRS GEO Flight-4 satellite is now ready for its planned Jan. 18 launch from Cape Canaveral Air Force Station, Florida, on a United Launch Alliance Atlas V rocket. Read More

In an unprecedented deep survey for small, faint objects in the Orion Nebula, astronomers using NASA’s Hubble Space Telescope have uncovered the largest known population of brown dwarfs sprinkled among newborn stars. Looking in the vicinity of the survey stars, researchers not only found several very-low-mass brown dwarf companions, but also three giant planets. They even found an example of binary planets where two planets orbit each other in the absence of a parent star.
