Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy: superflares.
These events occur when stars, for reasons that scientists still don’t understand, eject huge bursts of energy that can be seen from hundreds of light years away. Until recently, researchers assumed that such explosions occurred mostly on stars that, unlike Earth’s, were young and active.
Now, new research shows with more confidence than ever before that superflares can occur on older, quieter stars like our own—albeit more rarely, or about once every few thousand years.
Has NASA’s famed planet-hunting spacecraft met its end? Not so fast, say LASP researchers.
NASA recently announced that the Kepler Space Telescope, which searched for planets orbiting stars far away from Earth, had run out of fuel and would finish its nine-year mission. In response, many news outlets reported that Kepler was dead
But Lee Reedy, flight director for Kepler at LASP, said that the mission’s legacy is far from over. To date, Kepler has found a confirmed 2,662 planets beyond our solar system.
After nine years in deep space collecting data that indicate our sky to be filled with billions of hidden planets—more planets even than stars—NASA’s Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life.
Kepler, which was operated from LASP since its launch in March 2009, has opened our eyes to the diversity of planets that exist in our galaxy. The most recent analysis of Kepler’s discoveries concludes that 20 to 50 percent of the stars visible in the night sky are likely to have small, possibly rocky, planets similar in size to Earth, and located within the habitable zone of their parent stars. That means they’re located at distances from their parent stars where liquid water—a vital ingredient to life as we know it—might pool on the planet surface.
The most common size of planet Kepler found doesn’t exist in our solar system—a world between the size of Earth and Neptune—and we have much to learn about these planets. Kepler also found nature often produces jam-packed planetary systems, in some cases with so many planets orbiting close to their parent stars that our own inner solar system looks sparse by comparison.
Based on a recommendation from NASA’s 2014 Senior Review of its operating missions, the planet hunting Kepler space telescope has received a two-year extension to operate in a new two-wheel mode.
The approval allows the K2 mission to continue exoplanet discovery using two of its four original reaction wheels, and introduces new scientific observation opportunities to observe notable star clusters, young and old stars, active galaxies and supernovae.
The LASP-operated NASA Kepler spacecraft has discovered two planetary systems that include three super-Earth-sized planets in the “habitable zone,” where the surface temperature of a planet may sustain liquid water.
NASA has extended the Kepler mission through fiscal year 2016, adding four years to Kepler’s search for Earth-like planets in the Milky Way galaxy and allowing LASP to continue our work operating the spacecraft. A team of 20 University of Colorado students and 16 LASP professionals control the Kepler spacecraft from the LASP Mission Operations… Read more »
The NASA Kepler Mission won the highest honor for space programs at the 2012 Aviation Week Laureate Awards on March 7 in Washington, D.C. Students and professionals in the LASP Mission Operations Center control the Kepler spacecraft, which is surveying our region of the Milky Way galaxy for Earth-like planets. The Laureate Awards recognize individuals… Read more »
September 2011 marks a significant milestone for LASP, as our Mission Operations and Data Systems (MODS) team celebrates 15 years of continuous spacecraft operations. From long-standing science missions, such as ICESat, which have brought in important data over years—to newer missions, such as Kepler’s exciting search for Earth-like planets—LASP MODS has offered reliable spacecraft operations to agencies including NASA.
NASA’s Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star.
The transit signatures of two distinct planets were seen in the data for the sun-like star designated Kepler-9. The planets were named Kepler-9b and 9c. The discovery incorporates seven months of observations of more than 156,000 stars as part of an ongoing search for Earth-sized planets outside our solar system. The findings will be published in Thursday’s issue of the journal Science.
