How many new particles has the LHC discovered? The most widely known discovery is of course that of the Higgs boson. Less well known is the fact that, over the past 10 years, the LHC experiments have also found more than 50 new particles called hadrons. Coincidentally, the number 50 appears in the context of hadrons twice, as 2021 marks the…

Water worlds may be abundant in our galaxy
A new study suggests that our Milky Way galaxy is filled with planets like Earth, containing continents and oceans. If so, life might be common in the Mlilky Way. Source: https://earthsky.org/space/water-common-on-planets-pebble-accretion-milky-way…
Applying quantum computing to a particle process
A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that occur at CERN’s Large Hadron Collider. …

Scientists recently animated the hazards of being a blue whale that’s trying to avoid collisions with ships at sea. Source: https://www.livescience.com/whale-stress-animation.html
How to prevent crashes between orbiting satellites
Thousands more satellites will soon orbit Earth. We need better rules to prevent space crashes. Source: https://earthsky.org/space/satellites-prevent-space-crashes…
Rare images show role of collisions in galactic evolution
These six rare and exquisite images of galactic evolution were taken by the Hubble Space Telescope. They show what happens when galaxies collide and merge Source: https://www.newscientist.com/article/mg24933194-600-rare-images-show-role-of-collisions-in-galactic-evolution/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
When galaxies collide: Models suggest galactic collisions can starve massive black holes
It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that certain head-on collisions may in fact…
Physicists find best way for insects to avoid collisions when jumping
Equations show that jumping at 60 degrees relative to the horizontal helps insects avoid hitting obstacles – a finding that might help in the design of space exploration rovers Source: https://www.newscientist.com/article/2265565-physicists-find-best-way-for-insects-to-avoid-collisions-when-jumping/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
The first evidence of top quark production in nucleus-nucleus collisions
The Compact Muon Solenoid (CMS) Collaboration, a large group of researchers from different institutes worldwide, has recently gathered the very first evidence of top quark production in nucleus-nucleus collisions. Their work, outlined in a paper published in Physical Review Letters, was based on lead-lead collision data gathered by the CMS particle detector, at CERN’s Large Hadron Collider (LHC). …
C1-23152: An ancient galaxy that built itself
A popular theory of galaxy formation suggests that small galaxies merged to form larger ones. But galaxy C1-23152 – 12 billion light-years from Earth – apparently formed itself from gas in the early universe, via exceedingly rapid star formation.
