NASA’s Gemini Planet Imager discovers young Jupiter like planet

 

NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – One of the best ways to learn how our solar system evolved is to look at younger star systems in the early stages of development. Recently, a team of astronomers including NASA scientists discovered a Jupiter-like planet within a young system that could serve as a decoder ring for understanding how planets formed around our sun.

The new planet, called 51 Eridani (Eri) b, is the first exoplanet discovered by the Gemini Planet Imager (GPI), a new instrument operated by an international collaboration, and installed on the 8-meter Gemini South Telescope in Chile.

NASA study discovers Brown Dwarfs have strong Auroras around them

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Mysterious objects called brown dwarfs are sometimes called “failed stars.” They are too small to fuse hydrogen in their cores, the way most stars do, but also too large to be classified as planets.

But a new study in the journal Nature suggests they succeed in creating powerful auroral displays, similar to the kind seen around the magnetic poles on Earth.

“This is a whole new manifestation of magnetic activity for that kind of object,” said Leon Harding, a technologist at NASA’s Jet Propulsion Laboratory, Pasadena, California, and co-author on the study.

This artist's concept shows an auroral display on a brown dwarf. If you could see an aurora on a brown dwarf, it would be a million times brighter than an aurora on Earth. (Chuck Carter and Gregg Hallinan/Caltech)

NASA’s Kepler Space Telescope finds Earth size planet around a star like our sun in the Habitable Zone

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. This discovery and the introduction of 11 other new small habitable-zone candidate planets mark another milestone in the journey to finding another “Earth.”

The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030.

NASA to announce new discoveries by it’s planet seeking Kepler Space Telescope Thursday, July 23rd

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA will host a news teleconference at 9:00am PDT (noon EDT) Thursday, July 23rd, to announce new discoveries made by its planet-hunting mission, the Kepler Space Telescope.

The first exoplanet orbiting another star like our sun was discovered in 1995. Exoplanets, especially small Earth-size worlds, belonged within the realm of science fiction just 21 years ago. Today, and thousands of discoveries later, astronomers are on the cusp of finding something people have dreamed about for thousands of years — another Earth.

NASA’s New Horizons Spacecraft to be assisted by other missions during Pluto flyby

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – What’s icy, has “wobbly” potato-shaped moons, and is the world’s best-known dwarf planet? The answer is Pluto, and NASA’s New Horizons is speeding towards the edge of our solar system for a July 14th flyby.

It won’t be making observations alone; NASA’s fleet of observatories will be busy gathering data before and after to help piece together what we know about Pluto, and what features New Horizons data might help explain.

NASA’s Juno Spacecraft has one year remaining on flight to Jupiter

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – With just one year remaining in a five-year trek to Jupiter, the team of NASA’s Juno mission is hard at work preparing for the spacecraft’s expedition to the solar system’s largest planet.

The mission aims to reveal the story of Jupiter’s formation and details of its interior structure. Data from Juno will provide insights about our solar system’s beginnings, and what we learn from the mission will also enrich scientists’ understanding of giant planets around other stars.

NASA says June is month for Stargazing

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – If you love stargazing, there’s a date you need to mark on your calendar. It’s June.

That’s right, the whole month!

Throughout the month of June 2015, the two brightest planets in the night sky, Venus and Jupiter, are going to converge for a jaw-dropping close encounter. You don’t want to miss any of the action.

When the sun goes down, step outside and look west. You don’t have to wait until the sky fades to black. Venus and Jupiter are so bright, you can see then shining through the twilight.

NASA to suspend Communications to Mars Missions in June due to Mars Solar Conjunction

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In June 2015, Mars will swing almost directly behind the sun from Earth’s perspective, and this celestial geometry will lead to diminished communications with spacecraft at Mars.

The arrangement of the sun between Earth and Mars is called Mars solar conjunction. It occurs about every 26 months as the two planets travel in their sun-centered orbits. The sun disrupts radio communications between the planets during the conjunction period.

This diagram illustrates the positions of Mars, Earth and the sun during a period that occurs approximately every 26 months, when Mars passes almost directly behind the sun from Earth's perspective. (NASA/JPL-Caltech)

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

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

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 to increase search for Life on other Planets with NExSS Project

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA is bringing together experts spanning a variety of scientific fields for an unprecedented initiative dedicated to the search for life on planets outside our solar system.

The Nexus for Exoplanet System Science, or “NExSS”, hopes to better understand the various components of an exoplanet, as well as how the planet’s stars and neighbor planets interact to support life.

The search for life beyond our solar system requires unprecedented cooperation across scientific disciplines. NASA's NExSS collaboration includes those who study Earth as a life-bearing planet (lower right), those researching the diversity of solar system planets (left), and those on the new frontier, discovering worlds orbiting other stars in the galaxy (upper right).
