NASA - National Aeronautics and Space AdministrationWashington, D.C. – Barely 30 years ago, the only planets astronomers had found were located right here in our own solar system. The Milky Way is chock-full of stars, millions of them similar to our own sun. Yet the tally of known worlds in other star systems was exactly zero.

What a difference a few decades can make.

As 2014 unfolds, astronomers have not only found more than a thousand “exoplanets” circling distant suns, but also they’re beginning to make precise measurements of them.

Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In July 2015, NASA will discover a new world. No one knows what to expect when the alien landscape comes into focus. There could be icy geysers, towering mountains, deep valleys, even planetary rings.

At this point, only one thing is certain: Its name is Pluto.

On July 14th, 2015, NASA’s New Horizons spacecraft will make a close flyby of that distant world.

NASA reports discovery of Icy Planet in Binary Star System

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A newly discovered planet in a binary, or twin, star system located 3,000 light-years from Earth is expanding astronomers’ notions of where Earth-like — and even potentially habitable — planets can form, and how to find them.

At twice the mass of Earth, the planet orbits one of the stars in the binary system at almost exactly the same distance at which Earth orbits the sun. However, because the planet’s host star is much dimmer than the sun, the planet is much colder than Earth — a little colder, in fact, than Jupiter’s icy moon Europa.

This artist's rendering shows a newly discovered planet (far right) orbiting one star (right) of a binary star system. The discovery, made by a collaboration of international research teams and led by researchers at The Ohio State University, expands astronomers' notions of where to look for planets in our galaxy. The research was funded in part by NASA. (Cheongho Han, Chungbuk National University, Republic of Korea)

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA successfully launched its first spacecraft dedicated to studying atmospheric carbon dioxide at 2:56am PDT (6:56am CDT) Wednesday.

The Orbiting Carbon Observatory-2 (OCO-2) raced skyward from Vandenberg Air Force Base, California, on a United Launch Alliance Delta II rocket. Approximately 56 minutes after the launch, the observatory separated from the rocket’s second stage into an initial 429-mile (690-kilometer) orbit.

NASA reports Rosetta spacecraft speeding toward target Comet

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Less than half the distance between Earth and moon separates Rosetta from its destination, comet 67P/Churyumov-Gerasimenko. The European Space Agency’s (ESA) spacecraft will become the first to orbit a comet and land a probe on its nucleus. It is beginning observations and sending science data back to Earth.

Recent images from Rosetta’s Onboard Scientific Imaging System (OSIRIS) indicate that the comet is currently at rest — no longer showing signs of an extended dust coma surrounding its nucleus.

This image of comet 67P/Churyumov-Gerasimenko was taken by the Onboard Scientific Imaging System (OSIRIS) on the European Space Agency's Rosetta spacecraft on June 4, 2014. (ESA/Rosetta/MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

NASA uses ground radar to capture images of Asteroid as it passes near Earth

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8th, 2014, the new views of the object designated “2014 HQ124″ are some of the most detailed radar images of a near-Earth asteroid ever obtained.

The radar observations were led by scientists Marina Brozovic and Lance Benner of NASA’s Jet Propulsion Laboratory, Pasadena, California. The JPL researchers worked closely with Michael Nolan, Patrick Taylor, Ellen Howell and Alessondra Springmann at Arecibo Observatory in Puerto Rico to plan and execute the observations.

NASA’s Mars Curiosity rover captures images of the planet Mercury passing in front of the Sun

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has imaged the planet Mercury passing in front of the sun, visible as a faint darkening that moves across the face of the sun.

This is the first transit of the sun by a planet observed from any planet other than Earth, and also the first imaging of Mercury from Mars.

Mercury fills only about one-sixth of one pixel as seen from such great distance, so the darkening does not have a distinct shape, but its position follows Mercury’s expected path based on orbital calculations.

NASA’s Kepler Space Telescope discovers Rocky Planet that baffles Astronomers

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed.

“We were very surprised when we realized what we had found,” said astronomer Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts, who led the analysis using data originally collected by NASA’s Kepler space telescope.

Planet formation theorists are challenged to explain how such a massive world could have formed. (Harvard-Smithsonian Center for Astrophysics/David Aguilar)

NASA Earth Science study uses UAVSAR imager to take close look at Volcanoes in Central, South America

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A NASA-developed airborne imager called a synthetic aperture radar took a detailed look at volcanoes in Central and South America during an Earth science study in late April and early May 2014.

The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, was flown on NASA’s C-20A. The 29-day deployment ended May 6th when the aircraft returned to its base in Palmdale, California, after 19 flights totaling 97 hours in the air.

This false-color image of Peru's Ubinas volcano was acquired on April 14, 2014, by NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR. (NASA/JPL-Caltech)

NASA’s Cassini spacecraft takes photo of Planet Uranus from Saturn

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft has captured its first-ever image of the pale blue ice-giant planet Uranus in the distance beyond Saturn’s rings.

The robotic spacecraft briefly turned its gaze away from the ringed beauty of Saturn on April 11th, 2014, to observe the distant planet, which is the seventh planet from the sun.

This view from NASA's Cassini spacecraft features a blue planet, but unlike the view from July 19, 2013 (PIA17172) that featured our home planet, this blue orb is Uranus, imaged by Cassini for the first time. (NASA/JPL-Caltech/Space Science Institute)
