Puzzling ‘cold quasar’ forming new stars in spite of active galactic...

IMAGE: Using NASA's SOFIA telescope, researchers from the University of Kansas have found CQ 4479, a galaxy which never had been closely studied before, to be generating new stars in spite... view more  Credit: NASA LAWRENCE -- Researchers from the University of Kansas have described a galaxy more than 5.25 billion light years away undergoing a rarely seen stage in its galactic life cycle. Their findings…

Researchers discovered solid phosphorus from a comet

An international study led from the University of Turku, Finland, discovered phosphorus and fluorine in solid dust particles collected from a comet. The finding indicates that all the most important elements necessary for life may have been delivered to the Earth by comets. Researchers have discovered phosphorus and fluorine in solid dust particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko. It takes the comet…

Rapid-forming giants could disrupt spiral protoplanetary discs

Giant planets that developed early in a star system's life could solve a mystery of why spiral structures are not observed in young protoplanetary discs, according to a new study by University of Warwick astronomers. The research, published today (26 November) in the Astrophysical Journal Letters and part supported by the Royal Society, provides an explanation for the lack of spiral structure that astronomers expect…

New Hubble data explains missing dark matter

IMAGE: This image shows the sky around the ultra diffuse galaxies NGC 1052-DF4 and NGC 1052-DF2. It was created from images forming part of the Digitized Sky Survey 2. NGC 1052-DF2... view more  Credit: ESA/Hubble, NASA, Digitized Sky Survey 2 Acknowledgement: Davide de Martin New data from the NASA/ESA Hubble Space Telescope provides further evidence for tidal disruption in the galaxy NGC 1052-DF4. This result explains…

Neutrinos yield first experimental evidence of catalyzed fusion dominant in many...

AMHERST, Mass. - An international team of about 100 scientists of the Borexino Collaboration, including particle physicist Andrea Pocar at the University of Massachusetts Amherst, report in Nature this week detection of neutrinos from the sun, directly revealing for the first time that the carbon-nitrogen-oxygen (CNO) fusion-cycle is at work in our sun. The CNO cycle is the dominant energy source powering stars heavier than…

The…

Solar CNO neutrinos observed for the first time

Scientists who are members of the Borexino Collaboration have provided the first experimental proof of the occurrence of the so-called CNO cycle in the Sun: They have managed to directly detect the distinctive neutrinos generated during this fusion process. This is an important milestone on the route to better understanding the fusion processes that occur in the Sun. At the same time, although the CNO…

Space travel can adversely impact energy production in a cell
