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......»»

Hubble and Webb probe surprisingly smooth disk around Vega
In the 1997 movie "Contact," adapted from Carl Sagan's 1985 novel, the lead character scientist Ellie Arroway (played by actor Jodi Foster) takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm of debris encircling.....»»
Creepy cosmic eyes stare out from space in Webb and Hubble image

Webb and Hubble examine spooky galaxy pair
Stare deeply at these galaxies. They appear as if blood is pumping through the top of a flesh-free face. The long, ghastly "stare" of their searing eye-like cores shines out into the supreme cosmic darkness......»»
Hubble captures a new view of galaxy M90
This NASA/ESA Hubble Space Telescope image features the striking spiral galaxy Messier 90 (M90, also NGC 4569), located in the constellation Virgo. In 2019, Hubble released an image of M90 created with Wide Field and Planetary Camera 2 (WFPC2) data t.....»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»
Hubble captures intricacies of R Aquarii, a symbiotic binary star roughly 700 light-years from Earth
The NASA/ESA Hubble Space Telescope has provided a dramatic and colorful close-up look at one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars. Hubble's images capture its details and its evolution is featur.....»»
Hubble captures image of a spectacular ‘stellar volcano’

Hubble captures spiral galaxy NGC 5248
The sparkling scene depicted in this NASA/ESA Hubble Space Telescope image is of the spiral galaxy NGC 5248, located 42 million light-years from Earth in the constellation Boötes. It is also known as Caldwell 45. The Caldwell catalog holds visually.....»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Hubble and New Horizons offer dual perspectives on Uranus to inform exoplanet research
NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study l.....»»
SCOTUS denial ends saga of Shkreli’s infamous 5,000% drug price scheme
The Supreme Court offered no explanation for denying the petition. The legal saga over Martin Shkreli's infamous 5,000 percent price hike of a life-saving anti-parasitic drug has.....»»
Cuffing season: An evolutionary explanation for why people want to settle down for the winter months
Does the effort you invest in seeking a romantic partner intensify as summer ends? During the colder, darker months, people have been known to engage in "cuffing season," which means attaching yourself to or having a physical relationship with someon.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Webb researchers discover lensed supernova, confirm Hubble tension
Measuring the Hubble constant, the rate at which the universe is expanding, is an active area of research among astronomers around the world who analyze data from both ground- and space- based observatories. NASA's James Webb Space Telescope has alre.....»»
Hubble captures stellar nurseries in majestic spiral galaxy IC 1954
This image from the NASA/ESA Hubble Space Telescope features the spiral galaxy IC 1954, located 45 million light-years from Earth in the constellation Horologium. It sports a glowing bar in its core, majestically winding spiral arms, and clouds of da.....»»
Saturday Citations: Octopuses as shift supervisors for fish; universe confounds standard model; extremely old cheese
