Who turned the lights on? The modern impact of light pollution on the night sky
1+ week, 4+ day ago (469+ words) A different approach to determining the impact of light is using humans and their biological light sensors " eyes. This methodology was utilised in Kyba et al. , getting participants to compare their night skies to reference images of known light pollution…...
JWST reveals the most detailed map yet of the cosmic web
2+ week, 3+ day ago (517+ words) The international research team, led by scientists at the University of California, Riverside, traced this enormous network back to a time when the universe was just one billion years old. The breakthrough came through COSMOS-Web, the largest survey conducted by…...
Largest black holes formed by violent mergers, rather than collapsing stars
3+ week, 2+ day ago (251+ words) The largest black holes in the Universe, detected through the ripples they create in spacetime, are not formed directly from collapsing stars, according to new research led by Cardiff University. Instead, these cosmic giants grow through a series of repeated,…...
Solar activity can predict when space junk falls to Earth
3+ week, 3+ day ago (436+ words) There have been a variety of solutions posed to reduce the amount of space junk, from robots that will capture the debris to using ion beams to bring junk into the Earth's lower atmosphere, where it burns up upon descent....
DAMPE telescope reshapes understanding of cosmic rays and their origins
4+ week, 1+ day ago (642+ words) The research, involving experts from the University of Geneva, identifies a shared feature across multiple types of high-energy particles. The findings have been peer-reviewed and published in Nature. The study focuses on cosmic rays, which are highly energetic particles that…...
New shield material thinner than a strand of hair, but blocks both cosmic electromagnetic waves and radiation
1+ mon, 2+ day ago (170+ words) Shielding materials are a necessity in key modern industrial settings-such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices-to protect both equipment and personnel from electromagnetic waves and radiation. But electromagnetic waves and neutron radiation can only be…...
DESI completes largest-ever map of the Universe " what has it discovered?
1+ mon, 2+ week ago (819+ words) Operating from the Kitt Peak National Observatory in Arizona, DESI has charted more than 47 million galaxies and quasars in three dimensions. The result is a high-resolution cosmic map that stretches across billions of years, offering scientists an unprecedented dataset to…...
Climate of Earth-like rocky exoplanets mapped for first time
1+ mon, 2+ week ago (321+ words) First discovered in 2000, TRAPPIST-1 is a red dwarf star and is thought to be about 3 billion years older than the Solar System. Further discoveries in 2016 and 2017 identified at least seven exoplanets in the star's orbit, all likely tidally locked and…...
The long road to Mars: Propulsion, physics and the logistics of getting there
1+ mon, 2+ week ago (1186+ words) In reality, future missions to Mars are a logistics problem shaped by physics. Distance, energy, time and mass define what is possible long before politics or budgets enter the equation. Mars sits, on average, about 225 million kilometres from Earth. That…...
Po ET telescope makes first observations in exoplanet research
1+ mon, 2+ week ago (525+ words) Po ET's main telescope, seen above being lowered into its dome, has a 60-cm mirror. Po ET also has a second smaller telescope that collects light from the entire disc of the Sun. Exoplanets " worlds outside our Solar System " are…...
