Exoplanet Measured with Remarkable Precision

Exoplanet Measured with Remarkable Precision | Space & Time | Scoop.it

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.

M82 SN2014J: NASA's Chandra Observatory Searches for Trigger of Nearby Supernova

M82 SN2014J: NASA's Chandra Observatory Searches for Trigger of Nearby Supernova | Space & Time | Scoop.it

On January 21, 2014, astronomers witnessed a supernova soon after it exploded in the Messier 82, or M82, galaxy. Telescopes across the globe and in space turned their attention to study this newly exploded star, including Chandra. Astronomers determined that this supernova, dubbed SN 2014J, belongs to a class of explosions called "Type Ia" supernovas.

Nasa validates 'impossible' space drive | Space & Time | Scoop.it

Nasa is a major player in space science, so when a team from the agency this week presents evidence that "impossible" microwave thrusters seem to work, something strange is definitely going on. Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion.

Mercury's magnetic field tells scientists how its interior is different from Earth's | Space & Time | Scoop.it

Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report.

Alien Atmospheres - Methane, CFCs and Signs of Extraterrestrial “Intelligence” | Space & Time | Scoop.it

Sometimes we get lucky: an exoplanet many light-years away passes in front of its star at the perfect angle. This transit allows us to read certain features of that planet’s atmosphere. The resulting spectra – lines made by molecules like oxygen and methane – allow us a peek into that planet’s chemical anatomy.

Hubble Finds Three Surprisingly Dry Exoplanets

Hubble Finds Three Surprisingly Dry Exoplanets | Space & Time | Scoop.it

The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to be ideal candidates for detecting water vapor in their atmospheres because of their high temperatures where water turns into a measurable vapor.

Cassini Tracks Clouds Developing Over a Titan Sea

 Cassini spacecraft recently captured images of clouds moving across the northern hydrocarbon seas of Saturn's moon Titan. This renewed weather activity, considered overdue by researchers, could finally signal the onset of summer storms that atmospheric models have long predicted.

In its weekly report issued on July 31, the U.S. Drought Monitor reported that 82 percent of the state of California was in an extreme drought and 58 percent was in exceptional drought—up from 79 and 36 percent just two weeks ago. The drying of farmlands and suburbs is mirrored by the shrinking of the state’s reservoirs.

NASA’s Mars Spacecraft Maneuvers to Prepare for Close Comet Flyby

NASA’s Mars Spacecraft Maneuvers to Prepare for Close Comet Flyby | Space & Time | Scoop.it

The comet’s nucleus will miss Mars by about 82,000 miles (132,000 kilometers), shedding material hurtling at about 35 miles (56 kilometers) per second, relative to Mars and Mars-orbiting spacecraft. At that velocity, even the smallest particle -- estimated to be about one-fiftieth of an inch (half a millimeter) across -- could cause significant damage to a spacecraft.

Rotating Shape Model of Rosetta's Comet Target

Images of comet 67P/Churyumov-Gerasimenko taken on July 14, 2014, by the OSIRIS imaging system aboard the European Space Agency's Rosetta spacecraft have allowed scientists to create this three-dimensional shape model of the nucleus. The full rotation of the nucleus around its spin axis, shown here, emphasizes the bi-lobate structure already observed with the camera.
