At the workshop “Chandra Science for the Next Decade” being held in Cambridge, Massachusetts, a new image was presented showing a supernova remnant called G11.2-0.3 obtained using NASA’s Chandra X-ray Observatory. For years these were considered the remnants of the supernova recorded by the Chinese in 386 A.D. and for this reason known as SN 386 but new exams indicate that it was a different supernova.
An article published in “The Astrophysical Journal Supplement Series” describes a research on brown dwarfs, objects on the border between stars and planets. A team of researchers led by Jacqueline Fahery of the Carnegie Institution examined the characteristics of 152 young brown dwarfs and concluded that their atmospheres’ properties might be the behind their differences.
An article published in the journal “Nature” describes a research about the molecular cloud located behind the Orion Nebula. A group of researchers used the HAWK-I instrument installed on ESO’s Very Large Telescope (VLT) and the ALMA radio telescope, both ESO’s, to look at key moments of astrochemical phenomena, meaning the chemical reactions that take place in space and in this case in that area and one day will lead to the birth of new stars.
An article accepted for publication in the journal “Physical Review Letters” describes a research on the distribution of matter in the universe made in a way different from usual. An international team of researchers studied cosmic voids as if they were photographic negatives from which they could get information about ordinary matter, dark energy and dark matter.
An article published in the journal “Geophysical Research Letters” describes a research in which computer models were used to simulate the possible past climate on the planet Venus. A team of scientists at NASA’s Goddard Institute for Space Studies (GISS) led by Michael Way concluded that perhaps two billion years ago on Venus there was an ocean of liquid water on the surface and the conditions were favorable to life.
