Led by researchers at the University of Maryland and Cornell University, the study charts temperatures across WASP-18b, a massive gas giant classified as an “ultra-hot Jupiter” located 400 light-years from Earth. The team applied a method known as 3D eclipse mapping, also called spectroscopic eclipse mapping, marking the first time this technique has been used to build a full 3D temperature map. The work expands on a 2D eclipse map the group released in 2023 using highly sensitive observations from NASA’s James Webb Space Telescope (JWST).
So, if an academic paper is published in an open journal by an average citizen with an obsession for learning from online sources. So, there are no credentials but a decent work history. A prestigious college downloads the paper. What are the possible reasons?
Using the world's most advanced radio telescopes, astronomers have discovered a spinning dead star so rare, strange and unique that they have dubbed it a "cosmic unicorn." The unique properties of this object, CHIME J1634+44, challenge our current understanding of spinning dead stars and their environments.
The Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, evolution, and current structure of the outer solar system.
A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is moving in rhythm with the giant planet. This object, called 2020 VN40, is the first confirmed body that orbits the sun once for every ten orbits Neptune completes.
Our circumstances here on the wondrous, life-supporting Earth can give us a false understanding of what the Universe is really like. But our blue-skied, temperate planet is the extreme exception when it comes to other worlds. There's nothing remotely like Earth in our Solar System, and exoplanet studies reinforce that idea. While some exoplanets have hints of habitability, most exoplanets are extremely inhospitable.
Astronomers have detected a giant exoplanet—between three and ten times the size of Jupiter—hiding in the swirling disk of gas and dust surrounding a young star.
With the recent first light milestone for the Vera Rubin Observatory, it's only a matter of time before one of astronomy's most long-awaited surveys begins. The Legacy Survey of Space and Time (LSST) is set to start on November 5, and will scan the sky of billions of stars for at least ten years.
A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation has finished, while a same-aged companion star in this double star system still has a planet-forming disk.
There’s a new object in the solar system headed toward the sun, and it may have come from interstellar space. We only know of two other interstellar objects that have entered into our solar system before, ‘Oumuamua and Comet 2I/Borisov. The nature of ‘Oumuamua is still a matter of debate, and the second was a comet from another solar system. And now we may have a third interstellar visitor. Currently named A11pl3Z, this object has a trajectory that suggests it didn’t originate inside our own solar system.
Some planets take the expression "you're your own worst enemy" to the extreme. At least, that's what astronomers found when they recently discovered a doomed planet clinging to its parent star so tightly that it's triggering explosive outbursts and destroying itself.
The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the satellites we use for navigation, communication and Earth observation every day.
Fireball sightings were reported in multiple states across the southeastern United States during the day on Thursday, which NASA determined was produced by an asteroidal fragment weighing over a ton and moving over 30,000 mph.
Washington (AFP) – The team behind the long-awaited Vera Rubin Observatory in Chile published their first images on Monday, revealing breathtaking views of star-forming regions as well as distant galaxies.
As we're approaching the summer solstice, I'm going to harden my heart to the fact that it won't be getting nice and dark until, like, ten where I'm at. What are you guys going to be looking for tonight? If you're not going out, do you have any recommendations?
Paris (AFP) – The Milky Way may not have a catastrophic collision with another huge galaxy as has been predicted, computer simulations revealed Monday, giving our home galaxy a coin-flip chance of avoiding destruction.
