This month's Sky Tour podcast starts with a solstice update and a rundown of lunar phases, then helps you find four planets in the evening sky along with the best stars and constellations of early summer. The post June 2019: Peekaboo Planets appeared first on Sky & Telescope. […]

Using Earth's most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one that is believed to have birthed the moons of Jupiter. […]

As if black holes weren't mysterious enough, astronomers have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away. […]

Astronomers have spotted a pair of supermassive black holes on a collision course in a galaxy 2.5 billion light-years away. Coincidentally, the pair will begin producing gravitational waves in roughly 2.5 billion years, the researchers estimate. The duo can be used to estimate how many supermassive black hole pairs are detectable in the nearby, present-day universe and when the historic first detection of the background 'hum' of their gravitational waves will be made. […]

The collision of two neutron stars (GW170817) flung out an extraordinary fireball of material and energy that is allowing a a team of astrophysicists to calculate a more precise value for the Hubble constant, the speed of the universe's expansion. Previous estimates put the value between 66 and 90 km/s/Mpc, which this team refined to between 65.3 and 75.6 km/s/Mpc. […]

Radio telescope observations have made it possible for astronomers to use mergers of neutron-star pairs as a valuable new tool for measuring the Universe's expansion. […]

Hundreds of demonstrators gathered Monday at the base of Hawaii's tallest mountain to protest the construction of a giant telescope on land that some Native Hawaiians consider sacred. […]

The Russian-German Spektrum-Roentgen-Gamma (SRG) space mission successfully lifted off from the Baikonur cosmodrome on Saturday, July 13 at 14:31. Onboard is the eROSITA X-ray telescope, which was developed and built by a consortium of German institutes supported by Deutsches Zentrum für Luft- und Raumfahrt (DLR) and led by the Max Planck Institute for Extraterrestrial Physics (MPE). Astronomers from the University of Bonn are involved in the scientific preparation and exploitation. 1.5 […]

Russia launched a space telescope Saturday from the cosmodrome in Baikonur, Kazakhstan, in a joint mission with Germany intended to map X-rays across the sky and replace a project lost in January. […]

The English rock band Joy Division released their debut studio album "Unknown Pleasures" 40 years ago. The front cover doesn't feature any words, only a now iconic black and white data graph showing 80 wiggly lines representing a signal from a pulsar in space. To mark the anniversary of the album, we recorded a signal from the same pulsar with a radio telescope in Jodrell Bank Observatory, only 14 miles (23 km) away from Strawberry Studios where the album was recorded. […]
