Supernovae death reveals link to stars' birth

Fri, 22 Sep 2017 07:50:01 EDT

It was previously thought that molecules and dust would be completely obliterated by the tremendous explosions of supernovae. Yet, for the first time, scientists have discovered that this is not actually the case.



Image: X-plane preliminary design model tests quiet supersonic technology

Fri, 22 Sep 2017 06:53:41 EDT

Samantha O'Flaherty, Test Engineer for Jacobs Technology Inc., finalizes the set-up of the Quiet Supersonic Technology (QueSST) Preliminary Design Model inside the 14- by- 22 Foot Subsonic Tunnel at NASA Langley Research Center. Over the next several weeks, engineers will conduct aerodynamic tests on the 15% scale model and the data collected from the wind tunnel test will be used to predict how the vehicle will perform and fly in low-speed flight.

Fri, 22 Sep 2017 02:20:19 EDT

By 2040, a hundred people will live on the Moon, melting ice for water, 3D-printing homes and tools, eating plants grown in lunar soil, and competing in low-gravity, "flying" sports.



In space capsules, little room but big improvement

Thu, 21 Sep 2017 15:30:01 EDT

In 1961, an American astronaut reached space for the first time and soared through the heavens in a gumdrop-shaped capsule.



Fast radio bursts may be firing off every second

Thu, 21 Sep 2017 13:01:52 EDT

When fast radio bursts, or FRBs, were first detected in 2001, astronomers had never seen anything like them before. Since then, astronomers have found a couple of dozen FRBs, but they still don't know what causes these rapid and powerful bursts of radio emission.



Hope to discover sure signs of life on Mars? New research says look for the element vanadium

Thu, 21 Sep 2017 11:03:36 EDT

The search for biology on neighbor planet Mars won't play out like a Hollywood movie starring little green men. Rather, many scientists agree if there was life on the Red Planet, it probably will present itself as fossilized bacteria. To find it, astrobiologists likely will need to decode the chemical analysis of rock samples performed by a rover (like the one NASA plans to send to Mars in 2020). Only then might humankind know conclusively that life exists beyond Earth.



Solar eruption 'photobombed' Mars encounter with Comet Siding Spring

Thu, 21 Sep 2017 09:43:08 EDT

When Comet C/2013 A1 (Siding Spring) passed just 140,000 kilometres from Mars on 19th October 2014, depositing a large amount of debris in the martian atmosphere, space agencies coordinated multiple spacecraft to witness the largest meteor shower in recorded history. It was a rare opportunity, as this kind of planetary event occurs only once every 100,000 years. However, scientists analysing the data have found that a very powerful Coronal Mass Ejection (CME) launched by the Sun also arrived at Mars 44 hours before the comet, creating significant disturbances in the martian upper atmosphere and complicating analysis of the data. Results describing the combined effects of the comet and the CME throughout the martian atmosphere are being presented in a special session at the European Planetary Science Congress (EPSC) 2017 in Riga on Thursday, 21st September.



New gravitational wave data analysis now underway

Thu, 21 Sep 2017 08:41:26 EDT

Penn State LIGO physicists are members of the LIGO-Virgo collaboration to detect and characterize gravitational waves. The collaboration now is completing a very exciting Second Observing Run that is drawing to a close on August 25, 2017.



Returning humanity to the Moon

Thu, 21 Sep 2017 06:50:26 EDT

In the first act of lunar exploration, Neil Armstrong and Buzz Aldrin were major characters. In setting its sights on the moon, ESA hopes to bring many more actors to this off-world stage.



Earth through different eyes

Thu, 21 Sep 2017 06:33:40 EDT

In the 1960s, photographs of Earth taken by the first astronauts captured the imaginations of people across the world. The pictures not only became icons for space exploration, but also the fragility of our planet. But astronauts were not the only ones with their eyes on Earth.



Hubble discovers a unique type of object in the Solar System

Wed, 20 Sep 2017 16:02:11 EDT

With the help of the NASA/ESA Hubble Space Telescope, a German-led group of astronomers have observed the intriguing characteristics of an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features, including a bright coma and a long tail. This is the first known binary asteroid also classified as a comet. The research is presented in a paper published in the journal Nature today.



Europe urged to reconsider pullout from 'Armageddon' asteroid mission

Wed, 20 Sep 2017 13:04:16 EDT

Space scientists urged Europe Wednesday to rethink its withdrawal from a futuristic, international dry-run for an Armageddon-like mission to deflect a space rock on a calamitous collision course with Earth.



Aligning the primary mirror segments of NASA's James Webb Space Telescope with light

Wed, 20 Sep 2017 12:11:40 EDT

Engineers at NASA's Johnson Space Center in Houston used light waves to align the James Webb Space Telescope's mirror segments to each other, so they act like a single, monolithic mirror in the cryogenic cold of the center's iconic Chamber A.

Wed, 20 Sep 2017 11:21:27 EDT

The most-studied galaxy in the universe—the Milky Way—might not be as "typical" as previously thought, according to a new study.



Work on China's mission to Mars 'well underway'

Wed, 20 Sep 2017 09:48:33 EDT

Space radiation is risky business for the human body

Wed, 20 Sep 2017 09:34:24 EDT

While people protect their eyes from the sun's radiation during a solar eclipse, NASA's Human Research Program (HRP) is working to protect the whole human body from radiation in space. Space radiation is dangerous and one of the primary health risks for astronauts.

Ageing star blows off smoky bubble

Wed, 20 Sep 2017 06:00:04 EDT

Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their life-cycles.



Possible explanation for the galaxy's cosmic radiation

Wed, 20 Sep 2017 05:40:18 EDT

Cassiopeia A is a famous supernova remnant, the product of a gigantic explosion of a massive star about 350 years ago. Although discovered in radio observations 50 years ago, we now know that its emitted radiation spans from radio through high-energy gamma rays. It is also one of the few remnants for which the birth date and the type of supernova are known. It was a type IIb, the result of a core collapse supernova explosion. The precise knowledge of its nature makes Cassiopeia A one of the most interesting and investigated objects in the sky, and in particular, the study of its connection with cosmic rays, subatomic particles that fill the galaxy with energies higher than anything achievable in laboratories on Earth.



Scientists have invented a new way to weigh intergalactic black holes

Wed, 20 Sep 2017 05:39:46 EDT

Astrophysicists from Moscow State University have found a new way to estimate the mass of supermassive black holes outside our galaxy, even if they are barely detectable. The results of the study were published in Astronomy and Astrophysics.



Giant antennas in New Mexico search for cosmic discoveries

Tue, 19 Sep 2017 16:30:04 EDT

Employing an array of giant telescopes positioned in the New Mexico desert, astronomers have started a massive surveying project aimed at producing the most detailed view ever made of such a large portion of space using radio waves emitted from throughout the Milky Way and beyond.



New research suggests Mercury's poles are icier than scientists thought

Tue, 19 Sep 2017 13:18:11 EDT

The scorching hot surface of Mercury seems like an unlikely place to find ice, but research over the past three decades has suggested that water is frozen on the first rock from the sun, hidden away on crater floors that are permanently shadowed from the sun's blistering rays. Now, a new study led by Brown University researchers suggests that there could be much more ice on Mercury's surface than previously thought.



The cosmic water trail uncovered by Herschel

Tue, 19 Sep 2017 10:20:04 EDT

During almost four years of observing the cosmos, the Herschel Space Observatory traced out the presence of water. With its unprecedented sensitivity and spectral resolution at key wavelengths, Herschel revealed this crucial molecule in star-forming molecular clouds, detected it for the first time in the seeds of future stars and planets, and identified the delivery of water from interplanetary debris to planets in our solar system.
