Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. A team of physicists now offers an explanation.

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.

The researchers say 3D visualization of hurricanes and storm surges allows them to understand how flooding will impact coastal communities by allowing them to vividly see how each building and road might be impacted by a given flood.

A study has revealed that fine particulate matter from 1980 to 2020 was associated with approximately 135 million premature deaths globally.

Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.

Research reveals a shocking discovery about the history of our universe: the Milky Way Galaxy's last major collision occurred billions of years later than previously thought.

In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can't see today.

A groundbreaking method of detecting high-frequency gravitational waves (HFGWs) has been proposed. The team's innovative approach may enable the successful detection of HFGWs by utilizing existing and technologically feasible astronomical telescopes in planetary magnetosphere, opening up new possibilities for studying the early universe and violent cosmic events in an effective and technically viable way.

Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.

New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars. The first ever star-by-star massive cluster-formation simulations revealed that sufficiently dense molecular clouds, the 'birthing nests' of star clusters, can give birth to very massive stars that evolve into intermediate-mass black holes.

Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.

Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.

According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.

Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.

The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.

Short but severe episodes of flooding from hurricanes in Texas and Florida triggered a nationwide increase in flood insurance sign-ups depending on how socially connected a county was to the flooded counties.

Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The results offer a new way to probe supermassive black holes and their evolution across the universe.
