The Second Exoplanet in the Proxima Centauri Planetary System
New observations of Proxima Centauri, the nearest star to the Solar System, located at a distance of 4.2 light years, have made it possible to reveal the presence of a candidate low-mass planet orbiting the star at a distance 1.5 times greater than that separating the Earth from the Sun.
Global Gaia campaign reveals secrets of stellar pair
A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star.
Two new rogue planets
Theories of planet formation predict the existence of free-floating planets that were ejected from their parent planetary systems and are floating alone through space. Astronomers from the Warsaw University Observatory have found two new rogue worlds. The discovery has been published in the journal “Astronomy & Astrophysics”.
Astronomers discover a new class of X-ray sources
Sun and other stars in the Milky Way emit radiation that can be detected by human eyes. Astronomers, however, know many celestial objects that can radiate their energy in the form of X-rays. An international team of scientists, which includes astronomers from the Astronomical Observatory of UW, reported in the “Nature Astronomy” journal the discovery of a new class of X-ray sources.
