A new possible explanation for the Hubble tension
The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values......»»
Rein tension may affect horses" behavior
In a pilot study carried out at the University of Helsinki, high rein tension was found to be associated with trotters opening their mouths, which indicates pain or discomfort in the mouth......»»
Hubble zooms into the rosy tendrils of Andromeda
Clusters of stars set the interstellar medium ablaze in the Andromeda galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way's closest major galaxy. It measures approximately 152,000 light-years across and, with almo.....»»
Hubble observes an oddly organized satellite galaxy
Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way's closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appea.....»»
Concord’s rocky launch is less complicated than you think
Players are jumping through hoops to explain why Sony's Concord is struggling to get off the ground, but maybe the explanation is simpler than it seems......»»
Study reveals isolation, endogamy and pathogens in early medieval Spanish community
An archaeogenetic study sheds new light on the isolated medieval community Las Gobas in northern Spain. Besides isolation and endogamy, researchers have also identified the variola virus, which can offer a new explanation of how smallpox entered Iber.....»»
Hubble traces star formation in nearby nebula NGC 261
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA's Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way's closest galactic com.....»»
Hubble captures unique ultraviolet view of a spectacular star cluster
Roughly 210,000 light-years away, the Small Magellanic Cloud (SMC) is one of our Milky Way galaxy's closest neighbors. In fact, this small galaxy is one of the Milky Way's "satellite" galaxies, which orbit our home spiral galaxy......»»
Hubble spots the Tucana Dwarf in the dark
A splatter of stars glows faintly at almost 3 million light-years away in this new image from NASA's Hubble Space Telescope. Known as the Tucana Dwarf for lying in the constellation Tucana, this dwarf galaxy contains a loose bundle of aging stars at.....»»
Astronomers think they’ve found a plausible explanation of the Wow! signal
Magnetars could zap clouds of atomic hydrogen, producing focused microwave beams. Enlarge / The Wow! signal, represented as "6EQUJ5," was discovered in 1977 by astronomer Jerry Ehman. (credit: Public domain) An unusually.....»»
Supercomputer simulations offer explanation for X-ray radiation from black holes
Researchers at the University of Helsinki have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from black hole surroundings. The radiation originates from the combined effect of the chaotic movements of ma.....»»
Hubble spots a cluster of emission nebulae within the Large Magellanic Cloud
A bubbling region of stars both old and new lies some 160,000 light-years away in the constellation Dorado. This complex cluster of emission nebulae is known as N11, and was discovered by American astronomer and NASA astronaut Karl Gordon Henize in 1.....»»
Hubble rings in a new galactic view
The subject of this NASA/ESA Hubble Space Telescope image is situated in the Perseus Cluster, also known as Abell 426, 320 million light-years from Earth. It's a barred spiral galaxy known as MCG+07-07-072, seen here among a number of photobombing st.....»»
New analysis of Webb data measures universe expansion rate, finds there may not be a "Hubble tension"
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have come up with different ans.....»»
Hubble spotlights a supernova
This NASA/ESA Hubble Space Telescope image features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. The image also captured a supernova, named SN 2022ADQZ, shini.....»»
Hubble images a pair of tiny dwarf galaxies
A pair of new Hubble images show small dwarf galaxies, one of which is thought to be the result of a historical merger......»»
The sun"s corona is weirdly hot, and Parker Solar Probe rules out one explanation
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures, according to University of Michigan research published in The Astrophysical Journal L.....»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young stars. These findings could b.....»»
Globular cluster NGC 6558 explored with Gemini Observatory and Hubble Space Telescope
Using the Gemini Observatory and the Hubble Space Telescope (HST), an international team of astronomers has investigated a Galactic globular cluster known as NGC 6558. Results of the new study, published July 22 on the pre-print server arXiv, deliver.....»»
Hubble images NGC 3430, a classic spiral galaxy
This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor......»»
Image: A Saturnian summer
NASA's Hubble Space Telescope captured this image of Saturn and its colossal rings on July 4, 2020, during summer in the gas giant's northern hemisphere. Two of Saturn's icy moons are also clearly visible: Mimas at right, and Enceladus at bottom......»»
