Astronomers have discovered a world that they believe has ideal conditions for a thick atmosphere and an ocean half the size of the Atlantic Ocean. The Exoplanet — a world that orbits a star other than the sun — is LHS 1140 b, and is located about 48 light-years from Earth, in the constellation Cetus. … Read more
Using the James Webb Space Telescope (JWST), astronomers have observed the dramatic “dance” between a supermassive black hole and two satellite galaxies. The observations could help scientists better understand how galaxies and supermassive black holes grew in the early universe. This particular supermassive black hole is feeding on surrounding matter, powering a bright quasar that … Read more

A hellish planet with a “hot Jupiter” relatively close to Earth would probably smell like rotten eggs if we ever made the trip there, new data from the James Webb Space Telescope (JWST) reveals. HD 189733 b is a gas giant located about 64 light-years away in the constellation Vulpecula. It orbits extremely close to … Read more
Protecting pensions: what tax changes could come under the new government? In tax year 23/24 I contributed approximately £100,000 to my pension, taking advantage of the abolition of the lifetime exemption and using unused exemptions from previous years. I want to withdraw my pension now to avoid possible tax changes or anti-forestalling legislation from a … Read more
Researchers using the James Webb Space Telescope have studied the interaction of a quasar with satellite galaxies, gaining crucial insights into the growth of galaxies in the early universe, the mass of black holes, and chemical evolution.

New observations of Jupiter’s Great Red Spot have revealed that the planet’s atmosphere above and around the infamous storm is surprisingly interesting and active. This image shows the region Webb observed – first the location on a NIRCam image of the entire planet (left), and then the region itself (right), imaged by Webb’s Near-InfraRed Spectrograph … Read more
It looks like a distant ring with three glittering jewels, but the latest image from the Webb Space Telescope (JWST) is actually the view of a distant quasar surrounded by a nearby elliptical galaxy. The telescope’s Mid-Infrared Instrument (MIRI) spotted the faint apparition during a study of dark matter and its distribution in the universe. … Read more
An international research team, led by the Italian National Astrophysical Institute (INAF), has used the James Webb Space Telescope (JWST) to capture an extraordinary event in the distant Universe: the dramatic interaction between a quasar and two massive satellite galaxies in the PJ308-21 system. This remarkable discovery provides new insights into the growth of galaxies … Read more
Map of the line emission from hydrogen (in red and blue) and oxygen (in green) in the PJ308-21 system, shown after masking the light from the central quasar (“QSO”). The different colors of the quasar’s host galaxy and companion galaxies in this map reveal the physical properties of the gas within it. Credit: Decarli/INAF/A&A 2024 … Read more
