Why Is It So Tricky to Show the Sun, Earth, and Moon in a Diagram?
In a nutshell, you can get the distances or the sizes right, but not both. Space is hard!.....»»
Proba-3 will use laser for millimeter precision in space
ESA's double-spacecraft precision formation flying mission, Proba-3, is due to be launched from India on 4 December. The spacecraft pair will employ a set of positioning technologies to keep formation in space and this image shows the most precise: a.....»»
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.....»»
Video: Our sun is the star in a new simulation
NASA supercomputers are shedding light on what causes some of the sun's most complex behaviors. Using data from the suite of active sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar d.....»»
Astronomers snap first up-close image of a star outside our galaxy
Astronomers have taken a detailed image of a star outside of the Milky Way for the first time......»»
Astronomers take first close-up picture of a star outside our galaxy
Located a staggering 160,000 light-years from us, the star WOH G64 was imaged thanks to the impressive sharpness offered by the European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI). The new observations reveal a star puffi.....»»
Predicting the next supernova explosion: New simulations reveal the physics of supernova shock breakout
Stars with masses between 10 and 30 times that of the sun, in their final evolutionary stages, form an iron core that ultimately collapses into a neutron star. This collapse releases a tremendous amount of gravitational potential energy through neutr.....»»
Q&A: Getting serious about atmospheric methane removal
Carbon dioxide, the most important man-made greenhouse gas, gets most of the attention in efforts to stem the effects of climate change. While methane is considered a much more potent greenhouse gas, it breaks down into carbon dioxide and water in th.....»»
Unlocking the secrets of the first quasars: How they defy the laws of physics to grow
In an article published in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our sun, formed so rapidly in less than a billion years after the Big Bang......»»
Novel AI algorithm captures photons in motion
Close your eyes and picture the iconic "bullet time" scene from "The Matrix"—the one where Neo, played by Keanu Reeves, dodges bullets in slow motion. Now imagine being able to witness the same effect, but instead of speeding bullets, you're watchi.....»»

U.N. statistics show progress toward the goal of gender equality but a long way left to go.....»»
Can going to a haunted house boost the immune system?
Study found marked decrease in inflammatory markers and white blood cells after visiting a haunted house. Spooky season has come and gone, but those Halloween revelers who took in.....»»
Video: Proba-3"s journey to see the sun"s corona
The double-satellite Proba-3 is the most ambitious member yet of ESA's Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimeter......»»
How humans evolved to be "energetically unique"
Humans, it turns out, possess much higher metabolic rates than other mammals, including our close relatives, apes and chimpanzees, finds a Harvard study. Having both high resting and active metabolism, researchers say, enabled our hunter-gatherer anc.....»»
Flies carry bacteria, and some are resistant to antibiotics—evidence from three South African hospices
Houseflies live close to humans and domesticated animals and because they are so mobile they can easily spread bacteria that make people sick......»»
Statistical approach improves models of atmosphere on early Earth and exoplanets
As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for modeling these reactions, developed by a team led.....»»
Expert explains effects of catastrophic weather events on forests and tree species
This year has seen its share of severe weather—but how do these powerful storms impact forests over the long term? A Virginia Tech forest health expert breaks down the long-term effects catastrophic weather events can have and how to revive hard-hi.....»»
New fossil reveals the evolution of flying reptiles
The pterosaurs are extinct flying reptiles that lived alongside their close relatives, the dinosaurs. The largest of these reached 10 m in wingspan, but early forms were generally limited to around 2 m. In a paper, a team led by paleontologist Dr. Da.....»»
A 150-million-year journey from the Jurassic to Exposition Park
150 million years ago, Laurasia .The massive neck dips, casting a curving shadow on the mossy ground. The dinosaur's jaws close around its prize. The creature lifts its head, nearly dainty in scale, and contentedly gnaws a mouthful of ferns......»»
