The search for the perfect coronagraph to find Earth 2.0
Studying exoplanets is made more difficult by the light from the host star. Coronagraphs are devices that block out the star light and both JWST and Nancy Grace Roman Telescope are equipped with them. Current coronagraphs are not quite capable of see.....»»
JWST observations explore molecular outflows of a nearby merging galaxy
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby merging galaxy known as NGC 3256. Results of the observational campaign, presented March 21 on the pre-print server arXiv, yield essential informa.....»»
As climate change and pollution imperil coral reefs, scientists are deep-freezing corals to repopulate future oceans
Coral reefs are some of the oldest, most diverse ecosystems on Earth, and among the most valuable. They nurture 25% of all ocean life, protect coasts from storms and add billions of dollars yearly to the global economy through their influences on fis.....»»
Image: Hubble finds a field of stars
This image from the NASA/ESA Hubble Space Telescope shows a globular cluster called NGC 1651. Like another recent globular cluster image, NGC 1651 is about 162,000 light-years away in the largest and brightest of the Milky Way's satellite galaxies, t.....»»
In a distant stellar system, the JWST sees the end of planet formation
Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky? Will they be in the habitable.....»»
Sleeping supermassive black holes awakened briefly by shredded stars
A new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem. CSOs are active galaxies that host supermassive black holes at their cores. Out of the.....»»
Astronomers discover 49 new galaxies in under three hours
An international team of astronomers has discovered 49 new gas-rich galaxies using the MeerKAT radio telescope in South Africa. Their research is published in Monthly Notices of the Royal Astronomical Society......»»
New nearby mini-Neptune exoplanet discovered
An international team of astronomers reports the discovery of a new mini-Neptune exoplanet orbiting a nearby star. The newfound alien world, designated TOI-4438 b is about 2.5 times larger than the Earth. The finding was detailed in a paper published.....»»
"Dark stars": Dark matter may form exploding stars, and observing the damage could help reveal what it"s made of
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galax.....»»
An account of Australia"s oldest, boldest trees
Every state and territory in Australia has got big things. Consider the big Merino ram, big chooks, big Ned Kelly, or even the big golden guitar......»»
Four new DAQ white dwarfs discovered
Astronomers from the University of Oklahoma and their colleagues report the detection of four white dwarf stars of a recently discovered rare DAQ spectral subclass. The newfound white dwarfs are slightly more massive than the sun. The finding was det.....»»
Unveiling the formation of the first galaxies
Utilizing high-resolution three-dimensional radiation hydrodynamics simulations and a detailed supernova physics model run on supercomputers, a research team led by Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (A.....»»
Across oceans and millennia: Decoding the origin and history of the bottle gourd
In a fascinating dive into the past, a team of researchers from the Boyce Thompson Institute (BTI) and USDA has uncovered intriguing details about the origins and spread of the bottle gourd, one of the oldest domesticated crops......»»
Astrophysicist"s research could provide a hint in the search for dark matter
Dark matter is one of science's greatest mysteries. It doesn't absorb, reflect or emit light, so we can't see it. But its presence is implied by the gravitational effects it appears to have on galaxies......»»
Largest-ever map of universe"s active supermassive black holes released
Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objec.....»»
JWST observations shed more light on the nature of a distant galaxy cluster
Astronomers from the Nanjing University in China and elsewhere have performed high-resolution observations of a distant galaxy cluster known as CL J1001+0220 using the James Webb Space Telescope (JWST). The observational campaign, described in a pape.....»»
Citizen astronomers and AI discover 30,000 ring galaxies
Building on the synergy between citizen astronomer classifications and AI, astronomers have discovered approximately 400,000 spiral galaxies and 30,000 ring galaxies in data from the Subaru Telescope. This is the first example of research building on.....»»
Earth"s earliest forest revealed in Somerset fossils
Scientists have discovered remnants of the Earth's oldest fossil forest on the north coast of Devon and Somerset in the U.K. The trees, which are about 390 million years old, are thought to have grown as part of an extensive forest covering the east.....»»
Ancient stone tools found in Ukraine date to over 1 million years ago, and may be oldest in Europe
Ancient stone tools found in western Ukraine may be the oldest known evidence of early human presence in Europe, according to research published Wednesday in the journal Nature......»»
New study helps pinpoint when oldest ‘star dune’ formed, and why it’s moving west
