This new and incredibly deep image from Hubble shows the dim and diffuse galaxy NGC 1052-DF4. New research presents the strongest evidence yet that this strange galaxy is basically devoid of dark matter (Credit: NASA/ESA/STScI/S. Danieli et al.) Astronomers have all but confirmed the universe has at least one galaxy […]
Which path should we take? Credit: Johannes Ludwig/Unsplash, FAL We’ve all but won the argument on climate change. The facts are now unequivocal and climate denialists are facing a losing battle. Concern has risen up the political agenda, and major economic institutions such as the World Trade Organisation and the Bank of England highlight the […]

Half of the 36 supersonic plasma jets that will make up the Plasma Liner Experiment at Los Alamos National Laboratory have been installed. The remaining jets will be added and fully spherical plasma liner experiments will commence by the end of 2020. Credit: Los Alamos National Laboratory The Plasma Liner […]
The slower ships go, the less they pollute Shipowners say they are trying to cut their heavy-polluting industry’s impact on the environment by using cleaner energy—but some have stalled over limiting the speed of ships. Led by the International Maritime Organization (IMO), the industry is considering several options to replace […]

Two galaxies in the process of merging. Credit: NASA/ESA/Hubble When two galaxies merge, there are brief periods of stellar baby booms. A group of astronomers led by Lingyu Wang (SRON Netherlands Institute for Space Research) has now used a sample of over 200,000 galaxies to confirm that galaxy mergers are […]
At some point in the next 10 million years, the giant asteroid might follow the little shard and slam into Earth’s atmosphere itself. A still from a video shows a fireball passing over Kyoto, Japan after 1 a.m. on April 28, 2017 (Image: © SonataCo Network) In the early morning […]

Adding fuel to the intellectual fire that Copernicus started, Tycho showed this “new star” was far beyond the Moon, and that […]
