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 views multi-generational cluster NGC 2419
This image from the NASA/ESA Hubble Space Telescope shows the globular star cluster NGC 2419. Globular clusters are both beautiful and fascinating. They are spherical groups of stars that orbit the center of a galaxy, and in the case of NGC 2419, tha.....»»
Hubble spots an ancient pair of supermassive black holes about to merge
Recently, astronomers using the Hubble Space Telescope spotted two quasars burning brightly in the night sky -- and they're on a collision course......»»
A new measurement could change our understanding of the universe
The universe is expanding, but how fast exactly? The answer appears to depend on whether you estimate the cosmic expansion rate—referred to as the Hubble's constant, or H0—based on the echo of the Big Bang (the cosmic microwave background, or CMB.....»»
Researchers reveal mechanism of polarized cortex assembly in migrating cells
The cell cortex is defined as a thin layer of filamentous actin, myosin motors, and regulatory proteins beneath the plasma membrane. Assembly and contraction of this actin meshwork generates cortical tension, which enables cells to resist external me.....»»
Saturn’s rings are raining down particles on its atmosphere
New research using the Hubble Space Telescope shows that Saturn's icy rings actually heat up its upper atmosphere......»»
Hubble views Z 229-15, an intriguing active galaxy
This luminous image from the NASA/ESA Hubble Space Telescope shows , a celestial object that lies about 390 million light-years from Earth in the constellation Lyra. Z 229-15 is one of those interesting celestial objects defined as several different.....»»
Micron Technology: China probes US chip maker for cybersecurity risks as tech tension escalates
China has launched a cybersecurity probe into Micron Technology, one of America's largest memory chip makers, in apparent retaliation after US allies in Asia and Europe announced new restrictions on the sale of key technology to Beijing......»»
California wants to build more solar farms but needs more power lines
Transmission is now a big tension point for clean energy developers across the US. Enlarge / Westlands Solar Park, near the town of Lemoore in the San Joaquin Valley of California, is the largest solar power plant in the United S.....»»
Balancing security risks and innovation potential of shadow IT teams
Shadow IT teams, also known as rogue IT teams, have grown in popularity in recent years due to the rise of cloud-based apps and remote work. However, this has led to operational tension and security risks within many businesses. 58% of SMBs have expe.....»»
Hubble observes ram pressure stripping in galaxy JW100
The galaxy JW100 (lower right) features prominently in this image from the NASA/ESA Hubble Space Telescope. The streams of star-forming gas dripping from the disk of the galaxy like streaks of fresh paint are formed by a process called ram pressure s.....»»
Technology leaders not taking sides in G2 tension by visiting China
Despite an escalating technology standoff between the US and China, top executives of multinational corporations are visiting China, showing their commitment to the East Asian country......»»
There’s a cosmic jellyfish in this week’s Hubble image
Jellyfish galaxies have a main body of stars, with tentacle-like structures reaching off away from the body in just one direction......»»
Scientists offer "non-alien explanation" for interstellar visitor
When the first object ever known to have visited the Earth's Solar System from outer space zoomed past in 2017, it was so strange that at least one leading astronomer was convinced it was an alien vessel......»»
We now know what caused comet ‘Oumuamua’s strange orbit
It wasn't aliens that sent an interstellar comet to visit our solar system. The explanation is a phenomenon called outgassing......»»
Hubble sees the changing seasons on Jupiter and Uranus
Our planet isn't the only place in the solar system with dramatic weather changes - Hubble recently captured seasonal changes to two of the outer planets......»»
Hubble monitors changing weather and seasons of Jupiter and Uranus
Ever since its launch in 1990, NASA's Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the largely gaseous outer planets and their ever-changing atmospheres. NASA spacecraft missions to the outer planets have give.....»»
Study suggests explanation for unusual radar signatures of icy satellites in the outer solar system
A study co-authored by Southwest Research Institute Senior Research Scientist Dr. Jason Hofgartner explains the unusual radar signatures of icy satellites orbiting Jupiter and Saturn. Their radar signatures, which differ significantly from those of r.....»»
A sparkling field of stars cluster together in Hubble image
A Hubble image of the galaxy Messier 55 shows a stunning sea of stars in an enormous group called a globular cluster......»»
A small, fuzzy dwarf galaxy in our neighborhood captured by Hubble
This week's image from the Hubble Space Telescope shows a galaxy in our backyard, cosmically speaking, taken as part of a project to image nearby galaxies......»»
Hubble captures a messy irregular galaxy which hosted a supernova
This week's image from the Hubble Space Telescope shows a spiral galaxy called NGC 5486, shot through with wisps of pink where new stars are being born......»»
