Can strongly Lensed Type 1a Supernovae resolve cosmology’s biggest controversy?

Image - This composite of two astrophysics simulations shows a Type Ia supernova (purple disc) expanding over different microlensing magnification patterns (colored fields). Because individual stars in the lensing galaxy can significantly change the brightness of a lensed event regions of the supernova can experience varying amounts of brightening and dimming, which scientists believed would be a problem for cosmologists measuring time delays. Using detailed computer simulations at NERSC, astrophysicists showed that this would have a small effect on time-delay cosmology. (Credit: Danny Goldstein/UC Berkeley)

Hubble Observes Exoplanet Atmosphere in more Detail than ever before

A team of British and American astronomers used data from several telescopes on the ground and in space -- among them the NASA/ESA Hubble Space Telescope -- to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth. The analysis of the spectrum showed a large amount of water in the exoplanet's atmosphere -- three times more than in Saturn's atmosphere. Credit: NASA, ESA, and G. Bacon (STScI)

Holding Hands can Sync Brainwaves, Ease Pain, study shows

Holding hands

Holding the hand of a loved one in pain can synchronize breathing, heart rate and brain wave patterns. The more empathy a comforting partner feels for a partner in pain, the more their brainwaves fall into sync. Increased brain synchronization is associated with less pain.

Reach for the hand of a loved one in pain and not only will your breathing and heart rate synchronize with theirs, your brain wave patterns will couple up too, according to a study published this week in the Proceedings of the National Academy of Sciences (PNAS).

The study, by researchers with the University of Colorado Boulder and University of Haifa, also found that the more empathy a comforting partner feels for a partner in pain, the more their brainwaves fall into sync...

Scientists have long wanted to retrieve rock samples from the Moon’s South Pole-Aitken basin, and a new study could be helpful in locating an ideal landing site. A detailed study of a giant impact crater on the Moon’s far side could provide a roadmap for future lunar explorers.

The study, by planetary scientists from Brown University, maps the mineralogy of the South Pole-Aitken (SPA) basin, a gash in the lunar surface with a diameter of ~2,500 kilometers (1,550 miles)...
