NASA data to decipher clouds of sand on distant planets
Brown dwarfs - celestial objects that fall between stars and planets - are shown in this illustration with a range of temperatures, from hottest (left) to coldest (right). The two in the middle represent those in the right temperature range for clouds made of silicates to form. (Illustration by NASA/JPL-Caltech) A new study led by researchers at Western University provides critical information on sand clouds observed in distant planets and helps affirm a larger theory of how planetary atmospheres work.

Early stone tools were not rocket science
Early stone tools were not rocket science
Archaeologically excavated stone tools - some as much as 2.6 million years old - have been hailed as evidence for an early cultural heritage in human evolution. But are these tools proof that our an-cestors were already becoming human, both mentally and culturally? Dr. Claudio Tennie und William Snyder from the Department of Early Prehistory and Quaternary Ecology at the University of Tü-bingen have tested this traditional interpretation in a study funded by the European Re-search Council.

World's largest and most sensitive dark matter detector comes to life
World’s largest and most sensitive dark matter detector comes to life
The world's most sensitive dark matter experiment has gathered its first result, moving us a step closer to understanding one of the biggest mysteries of the Universe. It shows the experiment is successfully operating after years of set up by a team involving UCL researchers. The international project "LUX-ZEPLIN Dark Matter Experiment (LZ)" based at the Sanford Underground Research Facility in South Dakota, US is intricately and innovatively designed to find direct evidence of dark matter - an invisible substance thought to make up most of the mass of the Universe.

Shedding light on comet Chury's unexpected chemical complexity
Shedding light on comet Chury’s unexpected chemical complexity
A team of researchers led by the University of Bern has for the first time identified an unexpected richness of complex organic molecules at a comet. This was achieved thanks to the analysis of data collected during ESA-s Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. Delivered to the early Earth by impacting comets, these organics may have helped to kick-start carbon-based life as we know it.

Reflecting on a revolutionary discovery
Reflecting on a revolutionary discovery
July 4 marked the 10th anniversary of the discovery of the Higgs boson, a key piece in understanding particle physics There was a bump in the middle of the night. On June 14, 2012, Johns Hopkins physics and astronomy professor Andrei Gritsan analyzed data in a small meeting room at the CERN in Switzerland.

Slow spin of early galaxy observed for the first time
Slow spin of early galaxy observed for the first time
One of the most distant known galaxies, observed in the very earliest years of the Universe, appears to be rotating at less than a quarter of the speed of the Milky Way today, according to a new study involving University of Cambridge researchers. For the study, published in The Astrophysical Journal Letters , an international team of researchers analysed data from a galaxy known as MACS1149-JD1 (JD1), obtained from observations by the Atacama Large Millimeter/submillimeter Array (ALMA), an assembly of radio telescopes in Chile.

Chandra Observatory shows black hole spins slower than its peers
Chandra Observatory shows black hole spins slower than its peers
Astronomers have made a record-breaking measurement of a black hole's spin, one of two fundamental properties of black holes. NASA's Chandra X-ray Observatory shows this black hole is spinning slower than most of its smaller cousins. This is the most massive black hole with an accurate spin measurement and gives hints about how some of the universe's biggest black holes grow.

Powerful Tonga volcano eruption triggered atmospheric gravity waves reaching the edge of space
Powerful Tonga volcano eruption triggered atmospheric gravity waves reaching the edge of space
Hunga Tonga-Hunga Ha-apai eruption in January was unique in observed science, creating waves that reverberated around Earth, reaching 100km into the ionosphere. The eruption of the Hunga Tonga-Hunga Ha-apai submarine volcano on 15 January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.

Simulate defense of the Earth
Simulate defense of the Earth
NASA's Double Asteroid Redirection Test (DART) mission is the world's first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS now show that instead of leaving behind a relatively small crater, the impact of the DART spacecraft on its target could leave the asteroid near unrecognizable.

A new planet hunter is on the watch
The Near InfraRed Planet Searcher instrument, designed in part at Laval University, has successfully made its first observations The Near InfraRed Planet Searcher (NIRPS) instrument, designed in part at the University of Montreal and Laval University, has successfully made its first observations. Installed on the European Southern Observatory's (ESO) 3.6-meter telescope at the La Silla Observatory in Chile, NIRPS' mission is to search for new exoplanets around stars in the solar neighborhood.

A sanitizer in the galactic centre region
Many of us have probably already - literally - handled the chemical compound iso-propanol: it can used as an antiseptic, a solvent or a cleaning agent. But this substance is not only found on Earth: researchers led by Arnaud Belloche from the Max Planck Institute for Radio Astronomy in Bonn have now detected the molecule in interstellar space for the first time.

Long-term liquid water also on non-Earth-like planets?
Long-term liquid water also on non-Earth-like planets?
Liquid water is an important prerequisite for life to develop on a planet. As researchers from the University of Bern, the University of Zurich and the National Centre of Competence in Research (NCCR) PlanetS report in a new study, liquid water could also exist for billions of years on planets that are very different from Earth.

Climate damage caused by growing space tourism needs urgent mitigation
Climate damage caused by growing space tourism needs urgent mitigation
A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL. Published today in the journal  Earth's Future , researchers from UCL, the University of Cambridge and Massachusetts Institute of Technology (MIT) used a 3D model to explore the impact of rocket launches and re-entry in 2019, and the impact of projected space tourism scenarios based on the recent billionaire space race.

Astronomers link 64 telescopes to observe the structure of the Universe ahead of the SKAO launch
An international team of astronomers have for the first time combined the power of 64 radio telescope dishes to detect the faint signatures of neutral hydrogen gas across cosmological scales. The feat was achieved using the South African-based MeerKAT telescope, a precursor to the world's largest radio observatory, the SKA Observatory (SKAO), which will probe the Universe in unprecedented detail.

Two new rocky planets found in the solar neighborhood
An international collaboration, involving the Stellar Astrophysics group of the Complutense University, has discovered two new super-Earths orbiting a bright red dwarf star located only 33 light-years away, making them the closest rocky planets ever found outside our solar system. Neither of the two worlds can harbor life.
