Astronomers have discovered the smallest and most massive white dwarf ever seen.
The exoplanet satellite hunter CHEOPS of the European Space Agency, in which the Instituto de Astrofísica de Canarias is participating along with other European institutions, has unexpectedly detected a third planet passing in front of its star while it was exploring two previously known planets around the same star.
Cosmic dawn, when stars formed for the first time, occurred 250 million to 350 million years after the beginning of the universe, according to a new study led by researchers at University College London and the University of Cambridge.
The open access Journal of Astronomical Telescopes, Instruments, and Systems has published a special section on the latest science, engineering, research, and programmatic advances of starshades, the starlight-suppression technology integral to extra-solar and exoplanet detection.
Quasars are very bright, distant and active supermassive black holes that are millions to billions of times the mass of the Sun.
Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems - within the small cosmic distance of 326 light-years - that could find Earth merely by watching our pale blue dot cross our sun.
We can't detect them yet, but radio signals from distant solar systems could provide valuable information about the characteristics of their planets.
New findings published this week in Physical Review Letters, Measurement of the Iron Spectrum in Cosmic Rays from 10--GeV/n to 2.0--TeV/n with the Calorimetric Electron Telescope on the International Space Station, suggest that cosmic ray nuclei of hydrogen, carbon and oxygen travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently.

Abu Dhabi, UAE: Trans-Neptunian Objects, small objects that orbit the sun beyond Neptune, are fossils from the early days of the solar system which can tell us a lot about its formation and evolution.
