NASA Jets Chase The Total Solar Eclipse

By: NASA Goddard

Originally published on Jul 25, 2017

For most viewers, the Aug. 21, 2017, total solar eclipse will last less than two and half minutes. But for one team of NASA-funded scientists, the eclipse will last over seven minutes. Their secret? Following the shadow of the Moon in two retrofitted WB-57F jet planes. Amir Caspi of the Southwest Research Institute in Boulder, Colorado, and his team will use two of NASA’s WB-57F research jets to chase the darkness across America on Aug. 21. Taking observations from twin telescopes mounted on the noses of the planes, Caspi will capture the clearest images of the Sun’s outer atmosphere — the corona — to date and the first-ever thermal images of Mercury, revealing how temperature varies across the planet’s surface.

NASA & TRAPPIST-1: A Treasure Trove of Planets Found

 

By: NASA Jet Propulsion Laboratory

Originally published on Feb 22, 2017

Seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone.

Over 21 days, NASA’s Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found.

The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium.

The system has been revealed through observations from NASA’s Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.

NASA’s Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA’s Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at Caltech in Pasadena. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.

Showstopper Nov. 14 Supermoon is the Closest Moon to Earth since 1948

 

By: NASA Goddard

Originally published on Nov 9, 2016

The moon is a familiar sight, but the days leading up to Monday, Nov. 14, promise a spectacular supermoon show. When a full moon makes its closest pass to Earth in its orbit it appears up to 14 percent bigger and 30 percent brighter, making it a supermoon. This month’s is especially ‘super’ for two reasons: it is the only supermoon this year to be completely full, and it is the closest moon to Earth since 1948. The moon won’t be this super again until 2034!

NASA just launched a spacecraft to steal some asteroid particles

 

By: The Verge

Originally published on Sep 9, 2016

NASA just successfully launched its OSIRIS-REx spacecraft on an Atlas V rocket. Now, the vehicle is on its way to scoop up pieces of an asteroid and bring them back to Earth, a journey that will take seven years to complete. But if successful, those asteroid pieces could tell researchers a lot about the early Solar System and how life got started on our own planet.

We Conquered Jupiter’: Juno Enters Orbit

 

By: NASA Jet Propulsion Laboratory

Originally published on Jul 6, 2016

A recap of the July 4 excitement as NASA’s Juno spacecraft entered orbit around Jupiter. After an almost five-year journey to the solar system’s largest planet, Juno successfully entered Jupiter’s orbit during a 35-minute engine burn. Confirmation that the burn had completed was received on Earth at 8:53 pm. PDT (11:53 p.m. EDT) Monday, July 4. For more about Juno, visit http://nasa.gov/juno and http://missionjuno.swri.edu.
