After 6 years, NASA’s Kepler space telescope has found over 1,000 planets and counting

 

Written by Whitney Clavin

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler spacecraft began hunting for planets outside our solar system on May 12th, 2009. From the trove of data collected, we have learned that planets are common, that most sun-like stars have at least one planet and that nature makes planets with unimaginable diversity.

Kepler launched on March 6th, 2009. Its mission was to survey a portion of our galaxy to determine what fraction of stars might harbor potentially habitable, Earth-sized exoplanets, or planets that orbit other stars.

NASA’s Hubble Space Telescope sees Halo of Gas surrounding Andromeda Galaxy

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Scientists using NASA’s Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and 1,000 times more massive than previously measured.

The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. This finding promises to tell astronomers more about the evolution and structure of majestic giant spirals, one of the most common types of galaxies in the universe.

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) hears the possible sounds of Dead Stars

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Peering into the heart of the Milky Way galaxy, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted a mysterious glow of high-energy X-rays that, according to scientists, could be the “howls” of dead stars as they feed on stellar companions.

“We can see a completely new component of the center of our galaxy with NuSTAR’s images,” said Kerstin Perez of Columbia University in New York, lead author of a new report on the findings in the journal Nature. “We can’t definitively explain the X-ray signal yet — it’s a mystery. More work needs to be done.”

NASA says Space Telescopes may use Glitter Clouds to find new Worlds in the future

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – What does glitter have to do with finding stars and planets outside our solar system? Space telescopes may one day make use of glitter-like materials to help take images of new worlds, according to researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California.

Standard telescopes use solid mirrors to image far-away objects. But the large, complex mirrors needed for astronomy can be quite expensive and difficult to construct. Their size and weight also add to the challenges of launching a space telescope in the first place.

This image shows white light reflected off of a glitter mirror onto a camera sensor. Researchers tested this in a laboratory as part of the concept of "Orbiting Rainbows," a low-cost solution for space telescope mirrors. (G. Swartzlander/Rochester Institute of Technology)

NASA’s Hubble Space Telescope has made a name for itself in the past 25 years

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – You know you’ve made it when people know you by your first name alone.

There’s Cher. Beyoncé. Ozzie. Angelina. Lebron. Oprah.

Add to that list “Hubble.”

NASA’s Hubble Space Telescope is more than just a famous telescope. It is a household word, known to people of all walks of life, of all ages, and all levels of scientific literacy. Very few can compete with Hubble in name recognition, and its cultural impact is comparable to the Apollo moon landings.

NASA missions have discovered an abundance of Water in our Solar System

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways.

“NASA science activities have provided a wave of amazing findings related to water in recent years that inspire us to continue investigating our origins and the fascinating possibilities for other worlds, and life, in the universe,” said Ellen Stofan, chief scientist for the agency. “In our lifetime, we may very well finally answer whether we are alone in the solar system and beyond.”

NASA reports Planck and Herschel Space Telescopes used to find Galaxy Clusters

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One telescope finds the treasure chest, and the other narrows in on the gold coins. Data from two European Space Telescope missions, Planck and Herschel, have together identified some of the oldest and rarest clusters of galaxies in the distant cosmos.

Planck’s all-sky images revealed the clumps of bright galaxies, while Herschel data allowed researchers to inspect the galactic gems more closely and confirm the discovery.

This map of the entire sky was captured by the European Space Agency's Planck mission. The band running through the middle corresponds to dust in our Milky Way galaxy. The black dots indicate the location of galaxy cluster candidates identified by Planck and subsequently observed by the European Space Agency's Herschel mission. (ESA and the Planck Collaboration/ H. Dole, D. Guéry & G. Hurier, IAS/University Paris-Sud/CNRS/CNES)

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) images now available Online to the Public

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Millions of images of celestial objects, including asteroids, observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following the restart of the asteroid-seeking spacecraft in December 2013 after a lengthy hibernation.

The collection of millions of infrared images and billions of infrared measurements of asteroids, stars, galaxies and quasars spans data obtained between December 13th, 2013, and December 13th, 2014.

The NEOWISE spacecraft viewed comet C/2014 Q2 (Lovejoy) on January 30, 2015, at a solar distance of 120 million miles (193 million kilometers). (NASA/JPL-Caltech)

NASA’s Wide-field Infrared Survey Explorer (WISE) discovers stars at the edge of the Milky Way Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers using data from NASA’s Wide-field Infrared Survey Explorer, or WISE, have found a cluster of stars forming at the very edge of our Milky Way galaxy.

“A stellar nursery in what seems to be the middle of nowhere is quite surprising,” said Peter Eisenhardt, the project scientist for the WISE mission at NASA’s Jet Propulsion Laboratory in Pasadena, California. “But surprises turn up when you look everywhere, as the WISE survey did.”

The newfound young star clusters lie thousands of light-years below the plane of our Milky Way galaxy, a flat spiral disk seen in this artist's conception. If alien lifeforms were to develop on planets orbiting these stars, they would have views of a portion, or all, of the galactic disk. (NASA/JPL-Caltech)

NASA reports Space Telescopes reveal fierce winds coming from Black Hole

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions — a phenomenon that had been suspected, but difficult to prove until now.

This discovery has given astronomers their first opportunity to measure the strength of these ultra-fast winds and prove they are powerful enough to inhibit the host galaxy’s ability to make new stars.
