Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics shed light on the growth of galaxies in these large cosmic ... Astronomy Dec 4, 2024 0 49 Investigating how the biggest galaxies...

The origin of the supermassive black holes that inhabit the centres of massive galaxies remains unclear1,2. Direct-collapse black holes—remnants of supermassive stars, with masses around 10,000 times that of the Sun—are ideal seed candidates3,4,5,6. However, their very existence and their ...
Such a tidal stream can maintain its identity for billions of years. To date, astronomers have now identified streams originating from 12 small galaxies that ventured too close to the much larger Milky Way. Six more streams are associated with globular clusters. It has been suggested that large...
While not of the same venerable age as the Royal Aeronautical Society, the Royal Aero Club can lay claim to a respectable antiquity having celebrated its golden jubilee on 24th September 1961. Registered on 29th October 1901, the Aero Cl... ...
Still, NASA and other entities keep careful track of all asteroids visible from Earth, and are actively engaged in discovering as many asteroids as possible — especially the ones that are larger and would pose more of a (theoretical) threat to Earth. Asteroid orbits are plotted and tracked ...
NASA’sHubble Space Telescopeis giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star. “We just don’t know very much about how giant planets grow,” said Brendan Bowler of the University of Texas at Austin. “Th...
To date only very few CO observations exist in this redshift range that spans nearly 25% of the universe’s age. Considerable evolution of the star formation rate is already observed during this period. 18 galaxies out of our sample of 30 are detected (of which 16 are new detections), ...
The field of galaxy formation and evolution synthesizes the physics of baryons and dark matter to describe the origin of systems such as the Milky Way and the enormous diversity of the galaxy population. The broad variation in possible formation histories and the wide range of cosmic environments...
Two models have been proposed to date to explain the co-existence of the two distinct ripple scales on Mars. Under the first model, large ripples would result from the continuous growth of small ripples from saltation-driven impact splash, enabled by low dynamic wind pressures on Mars (i.e....
