Eclipse data used to create musical composition

Science Daily - Mon, 08/21/2017 - 10:57am
Researchers have created an original music composition for Monday's eclipse. They uses drums, synthesized tones and other sounds to symbolize the movements of the sun and moon and the gradual darkness they will produce during the August 21 event.

Astrophysicist predicts detached, eclipsing white dwarfs to merge into exotic star

Science Daily - Fri, 08/18/2017 - 4:24pm
Astrophysicists have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.

Eclipse research: Following in the moon's slipstream to capture high-res sunspot images

Science Daily - Fri, 08/18/2017 - 4:24pm
While much of the research around the eclipse on Monday will focus on the effects of the Sun's brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.

Spoiler alert: Computer simulations provide preview of upcoming eclipse

Science Daily - Fri, 08/18/2017 - 9:21am
Scientists have forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the US, tracing a 70-mile-wide band across 14 states.

An unusual white dwarf may be a supernova leftover

Science Daily - Thu, 08/17/2017 - 2:17pm
Astronomers have identified a white dwarf star in our galaxy that may be the leftover remains of a recently discovered type of supernova.

Astrophysicists predict Earth-like planet in star system only 16 light years away

Science Daily - Thu, 08/17/2017 - 11:08am
Astrophysicists have predicted that an Earth-like planet may be lurking in a star system just 16 light years away. The team investigated the star system Gliese 832 for additional exoplanets residing between the two currently known alien worlds in this system. Their computations revealed that an additional Earth-like planet with a dynamically stable configuration may be residing at a distance ranging from 0.25 to 2.0 astronomical unit (AU) from the star.

Four Earth-sized planets detected orbiting the nearest sun-like star

Science Daily - Thu, 08/17/2017 - 9:55am
Astronomers have discovered four Earth-sized planets orbiting the nearest sun-like star, tau Ceti, which is about 12 light years away and visible to the naked eye. These planets have masses as low as 1.7 Earth mass, making them among the smallest planets ever detected around nearby sun-like stars. Two of them are super-Earths located in the habitable zone of the star, meaning they could support liquid surface water.

NASA Protects its super heroes from space weather

When astronauts travel in space they can't see or even feel radiation. However, NASA's Human Research Program (HRP) is studying the effects radiation plays on the human body and developing ways to monitor and protect against this silent hazard.

Supermassive black holes feed on cosmic jellyfish

Science Daily - Wed, 08/16/2017 - 1:46pm
Observations of 'Jellyfish galaxies' with ESO's Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly.

NASA, ESA spacecraft track solar storm through space

Science Daily - Wed, 08/16/2017 - 10:03am
Using seven spacecraft, along with computer models, scientists have pieced together the journey of a coronal mass ejection from the Sun outward to Mars, Comet 67P, Jupiter and even the New Horizons spacecraft now beyond Pluto.

Cassini says goodbye to a true Titan

Science Daily - Tue, 08/15/2017 - 3:02pm
Mere weeks away from its dramatic, mission-ending plunge into Saturn, NASA's Cassini spacecraft has a hectic schedule, orbiting the planet every week in its Grand Finale. On a few orbits, Saturn's largest moon, Titan, has been near enough to tweak Cassini's orbit, causing the spacecraft to approach Saturn a bit closer or a bit farther away. A couple of those distant passes even pushed Cassini into the inner fringes of Saturn's rings.

Cosmic magnifying lens reveals inner jets of black holes

Science Daily - Tue, 08/15/2017 - 1:38pm
Jet material ejected from a black hole is magnified in new observations from Caltech's Owens Valley Radio Observatory. This discovery provides the best view yet of blobs of hot gas that shoot out from supermassive black holes.
