Astronomers have detected the most distant known radio galaxy, a surprising discovery given the supermassive black hole powering the galaxy was actively accreting gas and dust when the Universe was in its infancy.
The Very Large Array radio telescope has made the first detection of a planetary-mass body with a magnetic field 200 times more powerful than Jupiter’s. But it’s not yet clear whether it’s a brown dwarf or a massive exoplanet.
Eta Carinae, one of the brightest, most massive stars in the Milky Way, famously erupted 170 years ago, producing huge clouds of expanding debris. Astronomers studying light echoes from the blast may have found an explanation.
Mission planners preparing for the New Horizons flyby of a Kuiper Belt object on 1 January will attempt to monitor starlight as it is blocked out by the probe’s target, Ultima Thule, to update critical navigation data. Updated 4 August
Astronomers studying the remnants of a collision between two stars have made the first direct detection of radioactive material outside Earth’s solar system, debris that was blasted into space from one star’s deep interior
NASA’s newest observatory in space has started its search for planets around other stars as astronomers zero in on worlds that are ripe for research by follow-up missions like the James Webb Space Telescope.
