Every year, thousands of satellites are launched into orbit around our planet. The result is an increasingly congested "space" above Earth populated by equipment that provides services to the surface. At the same time, these ...
When astronomers talk about directly imaging an exoplanet orbiting a faraway star, the analogy they most commonly use is trying to spot a firefly next to a massive searchlight. An Earth-like exoplanet is incredibly dim—usually ...
Amina Helmi's passion for the Milky Way is clear as soon as one steps into her small office at the University of Groningen, in the north of the Netherlands.
Electrons zipping through transistors, powering the screens on our smartphones. Light zooming from distant stars to Earth, moving faster than anything else in the universe. Protons enabling MRI machines to analyze people's ...
A team of researchers has discovered that winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery ...
Astronomers have built the first three-dimensional map of gas temperature in the space surrounding our solar system, revealing a far messier and more dynamic picture than current models predict. The study was submitted to ...
The infrared-sensitive James Webb Space Telescope (JWST) has conducted multiple surveys of the very distant universe, digging into what was happening in the first billion years after the Big Bang. As part of these deep surveys, ...
The spacecraft rushing to the rescue of an aging and sinking NASA telescope has run into its own problem.
In 2010, scientists waiting to use the William Herschel Telescope in the Canary Islands captured a brief 36 minutes of images of Venus. They were waiting for the sun to set so they could look at distant stars and dust disks ...
By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by ...
