Relationships between chemicals found on comets

Science Daily - Sat, 12/03/2016 - 3:45pm
A new study has revealed similarities and relationships between certain types of chemicals found on 30 different comets, which vary widely in their overall composition compared to one another. The research is part of ongoing investigations into these primordial bodies, which contain material largely unchanged from the birth of the solar system some 4.6 billion years ago.

A Triple Star is Born

New evidence on the formation of the solar system

Science Daily - Fri, 12/02/2016 - 10:10am
Scientists are using new computer models and evidence from meteorites to show that a low-mass supernova triggered the formation of our solar system.

Embryonic cluster galaxy immersed in giant cloud of cold gas

Science Daily - Thu, 12/01/2016 - 4:46pm
Astronomers studying a cluster of still-forming protogalaxies seen as they were more than 10 billion years ago have found that a giant galaxy in the center of the cluster is forming from a surprisingly-dense soup of molecular gas.

Climate cycles may explain how running water carved Mars' surface features

Science Daily - Thu, 12/01/2016 - 4:42pm
Dramatic climate cycles on early Mars, triggered by buildup of greenhouse gases, may be the key to understanding how liquid water left its mark on the planet's surface, according to a team of planetary scientists.

Tangled threads weave through cosmic oddity

Science Daily - Thu, 12/01/2016 - 12:02pm
New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The elliptical galaxy is a beautiful cosmic oddity with a bright core wrapped in system of dark, swirling, thread-like filaments.

Astronomers watch star clusters spewing out dust

Science Daily - Thu, 12/01/2016 - 11:55am
Galaxies are often thought of as sparkling with stars, but they also contain gas and dust. Now, a team of astronomers has used new data to show that stars are responsible for producing dust on galactic scales, a finding consistent with long-standing theory. Dust is important because it is a key component of rocky planets such as Earth.

Star of Bethlehem may not be a star after all

Science Daily - Thu, 12/01/2016 - 11:25am
Studying historical, astronomical and biblical records, Grant Mathews, University of Notre Dame professor, believes the event that led the Magi was an extremely rare planetary alignment occurring in 6 B.C., and the likes of which may never be seen again.

Milky Way over Shipwreck

It's a bird... It's a plane... It's the tiniest asteroid!

Science Daily - Wed, 11/30/2016 - 3:44pm
A research team has characterized the smallest known asteroid using Earth-based telescopes: Asteroid 2015 TC25 measures just 6 feet across, they report.

W5: The Soul of Star Formation

First signs of weird quantum property of empty space?

Science Daily - Wed, 11/30/2016 - 8:28am
By studying the light emitted from an extraordinarily dense and strongly magnetized neutron star, astronomers may have found the first observational indications of a strange quantum effect, first predicted in the 1930s. The polarization of the observed light suggests that the empty space around the neutron star is subject to a quantum effect known as vacuum birefringence.

NASA Saturn mission prepares for 'ring-grazing orbits'

Science Daily - Tue, 11/29/2016 - 10:29am
A thrilling ride is about to begin for NASA's Cassini spacecraft. Engineers have been pumping up the spacecraft's orbit around Saturn this year to increase its tilt with respect to the planet's equator and rings. And on Nov. 30, following a gravitational nudge from Saturn's moon Titan, Cassini will enter the first phase of the mission's dramatic endgame.

Arp 240: A Bridge between Spiral Galaxies from Hubble

APOD - Tue, 11/29/2016 - 9:07am

Low-mass supernova may have triggered formation of our solar system

Science Daily - Mon, 11/28/2016 - 11:15am
A research team has used new models and evidence from meteorites to propose that a low-mass supernova triggered the formation of our solar system.
