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 images spiral galaxy NGC 5643
The spiral galaxy NGC 5643 is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy's symmetrical form with two large, winding spiral arms that are clearly visi.....»»
Feast your eyes on 10 years of Hubble images of Jupiter, Saturn, Uranus, Neptune
The Hubble Space Telescope has been imaging the outer planets of our solar system for a decade, learning about their strange weather conditions......»»
Latest James Webb data hints at new physics in Universe’s expansion
These latest findings further support the Hubble Space Telescope's prior expansion rate measurements. Physicists have been puzzling over conflicting observational results pertaini.....»»
MAUVE: An ultraviolet astrophysics probe mission concept
For the past 30 years, NASA's Great Observatories—the Hubble, Spitzer, Compton, and Chandra space telescopes—have revealed some amazing things about the universe. In addition to some of the deepest views of the universe provided by the Hubble Dee.....»»
Hubble takes closest-ever look at a quasar
Astronomers have used the unique capabilities of NASA's Hubble Space Telescope to peer closer than ever into the throat of an energetic monster black hole powering a quasar. A quasar is a galactic center that glows brightly as the black hole consumes.....»»
New approach uses observed local supervoid to give expansion of the universe an extra push and solve the Hubble tension
Astronomers have known for a century that the universe is expanding. We can now trace this expansion over much of its almost 14 billion year history, with important constraints going back to just one second after the Big Bang! The expansion rate toda.....»»
Webb and Hubble snap the same object for two views of one galaxy
Two different space telescopes have looked at the same galaxy, so you can see the difference in how they observe the universe......»»
When club teammates become World Cup rivals: Research reveals hidden tension when coworkers compete
In today's interconnected professional world, employees often have affiliations outside their primary workplace. This phenomenon can be harmless—or even beneficial—until two employees find themselves representing rival entities......»»
Hubble finds sizzling details about young star FU Orionis
In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our sun. Unlike an exploding.....»»
Chandra and Hubble tune into "flame-throwing" Guitar Nebula
Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's Chandra X-ray Observatory and.....»»
Making Mars"s moons: Supercomputers offer "disruptive" new explanation
A NASA study using a series of supercomputer simulations reveals a potential new solution to a longstanding Martian mystery: How did Mars get its moons? The first step, the findings say, may have involved the destruction of an asteroid......»»
Dev + Sec: A collaborative approach to cybersecurity
The age-old tension between development and security teams has long been a source of friction in organizations. Developers prioritize speed and efficiency, aiming to deliver features and products quickly with a fast-paced, iterative development cycle.....»»
Solar wind power likely governs Uranus" thermosphere temperature
Uranus's upper atmosphere has been cooling for decades—and now scientists have shown why. Observations from Earth have shown Uranus' upper atmosphere has been cooling for decades, with no clear explanation......»»
Kinetic Alfvén waves may be key to mystery of solar corona heating
Syed Ayaz, a researcher at The University of Alabama in Huntsville (UAH), has published a paper in Scientific Reports that builds on an earlier first-of-its-kind study that examined kinetic Alfvén waves (KAW) as a possible explanation for why the so.....»»
Hubble captures barred spiral galaxy NGC 1672
This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celes.....»»
Hubble and Webb are the dream team—don"t break them up, researchers say
Many people think of the James Webb Space Telescope as a sort of Hubble 2. They understand that the Hubble Space Telescope (HST) has served us well but is now old and overdue for replacement. NASA seems to agree, as they have not sent a maintenance m.....»»
A single atom can change the directional profile of the light emitted in scanning tunneling microscopes
Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM.....»»
Japan launches a defense satellite carried by a new flagship H3 rocket
Japan launched a defense satellite designed for information-gathering and military operations on a new flagship H3 rocket on Monday, as the country seeks to build up its military capability amid growing tension in the region......»»
