Vast luminous nebula poses a cosmic mystery

Science Daily - Thu, 02/23/2017 - 12:43pm
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an 'enormous Lyman-alpha nebula' (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed.

Space dust deploy bubble parachutes on their fiery descent, scientists discover

Science Daily - Thu, 02/23/2017 - 10:20am
Bubbles acting like parachutes are deployed by some cosmic dust particles on their entry into Earth’s atmosphere, preventing them from burning up.

Daphnis and the Rings of Saturn

NASA telescope reveals largest batch of Earth-size, habitable-zone planets around single star

Science Daily - Wed, 02/22/2017 - 1:09pm
NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.

An Active Night over the Magellan Telescopes

The night sky is always changing. The night sky is always changing.


Surprising dunes on comet Chury

Science Daily - Wed, 02/22/2017 - 8:28am
Surprising images from the Rosetta spacecraft show the presence of dune-like patterns on the surface of comet Chury. Researchers have studied the available images and modeled the outgassing of vapor to try to explain the phenomenon. They show that the strong pressure difference between the sunlit side of the comet and that in shadow generates winds able to transport grains and form dunes.

Possible dark matter ties in Andromeda Galaxy

Science Daily - Wed, 02/22/2017 - 8:23am
NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Brightest neutron star yet has a multipolar magnetic field

Science Daily - Tue, 02/21/2017 - 4:15pm
Scientists have identified a neutron star that is consuming material so fast it emits more x-rays than any other. Its extreme brightness can only be explained if the star has a complex multipolar magnetic field, the researchers say.

Prediction: More gas-giants will be found orbiting Sun-like stars

Science Daily - Tue, 02/21/2017 - 1:07pm
New planetary formation models indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn.

Experiments call origin of Earth's iron into question

Science Daily - Tue, 02/21/2017 - 11:07am
New research reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.

Almost Three Tails for Comet Encke

APOD - Tue, 02/21/2017 - 9:07am

How can a comet have three tails? How can a comet have three tails?


Mapping the family tree of stars

Science Daily - Mon, 02/20/2017 - 7:16pm
Astronomers are borrowing principles applied in biology and archaeology to build a family tree of the stars in the galaxy. By studying chemical signatures found in the stars, they are piecing together these evolutionary trees looking at how the stars formed and how they are connected to each other. The signatures act as a proxy for DNA sequences. It's akin to chemical tagging of stars and forms the basis of a discipline astronomers refer to as Galactic archaeology.

Why are there different 'flavors' of iron around the Solar System?

Science Daily - Mon, 02/20/2017 - 1:47pm
New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.

Black Sun and Inverted Starfield

Examining exploding stars through the atomic nucleus

Science Daily - Sun, 02/19/2017 - 4:51pm
Imagine being able to view microscopic aspects of a classical nova, a massive stellar explosion on the surface of a white dwarf star (about as big as Earth), in a laboratory rather than from afar via a telescope. Cosmic detonations of this scale and larger created many of the atoms in our bodies. A safe way to study these events in laboratories on Earth is to investigate the exotic nuclei or 'rare isotopes' that influence them.

Hubble spotlights a celestial sidekick

Science Daily - Fri, 02/17/2017 - 4:09pm
Technically, this picture is merely a sidekick of the actual object of interest -- but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own.

Minor planet named Bernard

Science Daily - Fri, 02/17/2017 - 9:59am
A minor planet in the Solar System will officially be known as Bernardbowen from today after Australian citizen science project theSkyNet won a competition to name the celestial body.
