An article published in “The Astrophysical Journal” describes the study of the planet’s characteristics circumbinary Kepler-1647b. By using the Kepler space telescope NASA, a team of scientists at NASA’s Goddard Space Flight Center and the San Diego State University led by Veselin Kostov discovered this planet that orbits two stars. This is not the first case of this kind but it’s the biggest and its year is longer, about three Earth’s years.
An article accepted for publication in “The Astrophysical Journal” describes a research based on observations made with the Hubble Space Telescope that suggests that the universe is expanding at a faster rate than expected. A team of astronomers led by Nobel laureate Adam Riess measured the distance of stars in nineteen galaxies with the best accuracy ever achieved to obtain this surprising result.
An article published in the journal “Nature Geoscience” describes a study on the relationship between super solar flares of a few billion years ago and the emergence of life forms on Earth. According to a team of NASA scientists led by Vladimir Airapetian those gigantic storms provided the energy needed to warm up the Earth and to trigger some chemical reactions needed to form complex molecules such as RNA and DNA on which life is based.
An article published in “The Astrophysical Journal Letters” describes a research on the Tycho supernova remnant. That explosion was seen on Earth in 1572 in an event well documented. The expansion of the remaining materials is still interesting and a team of astronomers studied it with NASA’s Chandra X-ray Observatory, the NSF’s Karl G. Jansky Very Large Array (VLA) and many other telescopes to create a kind of film that shows it.
An article published in the journal “Nature” describes the discovery of a solar system with three rocky planets that orbit the star TRAPPIST-1, a really small ultra-cool dwarf. A team led by Michaël Gillon of the Institut d’Astrophysique et Géophysique at the University of Liège in Belgium, found these planets with sizes and surface temperatures similar to those of the Earth using the TRAPPIST telescope at ESO’s La Silla Observatory in Chile.
