Supernovae death reveals link to stars’ birth

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

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. 

Fast radio bursts may be firing off every second

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

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

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

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.
