Planet Earth is going to get an exceptional conveyance—the greatest example yet from a space rock. A NASA rocket will fly by Earth on Sunday and drop off what is generally anticipated to be basically a cupful of rubble it snatched from the space rock Bennu, finishing off a seven-year mission. The example container will drop into the Utah desert as its mothership, the Osiris-Rex shuttle, zooms off for an experience with another space rock. Researchers expect to get about a half pound (250 grams) of stones and residue, significantly more than the teaspoon or so brought back by Japan

Over billions of years, galaxies expand and change by absorbing close companions and merging with other galaxies. The early stages of this galactic growth process are showcased in a new image taken with the US Department of Energy's (DOE) Dark Energy Camera (DECam) mounted on the National Science Foundation's (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab. About 55 million light-years away, in the direction of the southern constellation Eridanus (the river), is the huge barred spiral galaxy NGC 1532, sometimes referred to as Haley's Coronet. Edge-on views from Earth reveal

Astronomers have found the largest store of hot gas to date in the still-forming galaxy cluster around the Spiderweb galaxy using the Atacama Large Millimeter/submillimeter Array (ALMA), of which ESO is a partner. Galaxies are among the largest things known to exist in the universe, and this finding, which was published in Nature today, shows just how early these structures start to emerge. As the name implies, galaxy clusters house hundreds or perhaps thousands of galaxies. The huge “intracluster medium” (ICM) of gas that fills the space between the galaxies in the cluster is also present in them. In fact,

Black holes are among the most exotic phenomena in the universe because they are enigmatic, fascinating, and unavoidable. The chirp sound that two black holes make when they merge can be heard using gravitational-wave detectors; about 70 such chirps have been discovered so far. A team of researchers at the Heidelberg Institute for Theoretical Studies (HITS) now predicts that in this “ocean of voices” chirps preferentially occur in two universal frequency ranges. The study has been published in The Astrophysical Journal Letters. In addition to earning Einstein the 2017 Nobel Prize in Physics, the discovery of gravitational waves in 2015

To shed light on the beginnings of life on Earth, scientists run computational simulations for biological compounds found in meteorites. The only version of every biological amino acid found on Earth is left-handed, although the underlying cause of this discovery is unclear. Japanese researchers recently discovered fresh information regarding the cosmic origin of this asymmetry. They performed physics-based simulations using the amino acids present in the Murchison meteorite as a basis, and the results suggested that the precursors to biological amino acids may have controlled amino acid chirality throughout the early galaxy evolution. If you look at your hands, you

This time, using information on the structure of galaxy clusters, cosmologists have discovered fresh support for the mainstream model of cosmology. In a recent study, a group of physicists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory made careful measurements of the X-ray emission from galaxy clusters, which showed the distribution of stuff within them. The information also enabled researchers to evaluate the dominant hypothesis of the universe's structure and evolution, called Lambda-CDM. Getting there wasn't an easy task, however. Here's the trouble: When the force of gravity, which keeps the entire system together, balances the

Researchers at the Oak Ridge National Laboratory, under the direction of Kelly Chipps, have created a characteristic nuclear reaction that takes place on the surface of a neutron star that is consuming mass from a companion star. Their accomplishment advances knowledge of stellar mechanisms that produce a range of nuclear isotopes. “Neutron stars are really fascinating from the points of view of both nuclear physics and astrophysics,” said ORNL nuclear astrophysicist Kelly Chipps, who led a study published in Physical Review Letters. “A deeper understanding of their dynamics may help reveal the cosmic recipes of elements in everything from people

The booked sendoff of the X-Beam Imaging and Spectroscopy Mission (XRISM) and the Savvy Lander for Researching the Moon (Thin), which installed the H-IIA Sendoff Vehicle No. 47 (H-IIA F47) on August 28, 2023, has been cleaned because of the way that the upper breezes didn't meet the sendoff conditions. At the point when a space office like NASA or JAXA (Japan Aviation Investigation Organization) "scours" a launch, it implies they have chosen to drop or delay a planned rocket launch. This choice can arise from different variables. Unfriendly weather patterns, like high breezes or lightning, can jeopardize the mission.

Researchers from MIT, Nanoplanet Consulting, Harvard University, and the University of Alberta have discovered through lab testing that conditions in Venus' clouds may be favorable for harboring life. The group discusses the experiments they carried out in their lab and the outcomes in their report that was published in Proceedings of the National Academy of Sciences. According to earlier studies, Venus' surface averages 462°C, which is significantly too hot for life to exist there. However, the planet's atmosphere is much cooler, particularly in its cloud temperatures there are just 30°C to 70°C, well within a range that could support life.

Another study discovered that concentrations of potentially hazardous substances in dust collected from air filtration frameworks on the International Space Station (ISS) outnumber those found in floor dust from many American homes. In the principal investigation of its sort, researchers dissected an example of residue from air channels inside the ISS and found degrees of natural foreign substances that were higher than the middle qualities tracked down in US and Western European homes. Distributing their outcomes in Natural Science and Innovation Letters, specialists from the College of Birmingham, UK, as well as the NASA Glenn Exploration Center, U.S., say their
