University of British Columbia astronomy student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA’s Kepler mission. Over its original 4-year mission, the Kepler satellite looked for planets, especially those that lie in the “Habitable Zones” of their stars, where liquid water could exist ...
Astronomers have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type. It means that a single year for this hot Jupiter — a gas giant similar in size and composition to Jupiter in our own solar system — passes in less ...
Using ESO’s Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star’s surface show not only the fading red supergiant, but also how its apparent shape is changing. Betelgeuse has been a beacon in the night sky ...
An international team of astronomers led by scientists at the University of California, Riverside, has found an unusual monster galaxy that existed about 12 billion years ago when the universe was only 1.8 billion years old. Dubbed XMM-2599, the galaxy formed stars at a high rate and then died. Why it suddenly stopped forming stars is ...
It’s “almost a racing certainty” there’s alien life on Jupiter’s moon Europa — and Mars could be hiding primitive microorganisms, too. That’s the view of leading British space scientist Professor Monica Grady, who says the notion of undiscovered life in our galaxy isn’t nearly as far-fetched as we might expect. Professor Grady, a Professor of Planetary ...
“Super-Puffs” may sound like a new breakfast cereal. But it’s actually the nickname for a unique and rare class of young exoplanets that have the density of cotton candy. Nothing else like them exists in our solar system. New data from NASA’s Hubble Space Telescope have provided the first clues to the chemistry of two of ...
A type of Martian aurora first identified by NASA’s MAVEN spacecraft in 2016 is actually the most common form occurring on the Red Planet, according to new results from the mission. The Martian aurora is known as a proton aurora and can help scientists track water loss from Mars’ atmosphere. On Earth, auroras are commonly seen ...
Scientists have improved a computer program that helps simulate the behavior of photons when interacting with hydrogen spilled in intergalactic space. The results have been published in the scientific journal Monthly Notices of the Royal Astronomical Society. Andrey Savelyev, associate professor of the Institute of Physical and Mathematical Sciences and Information Technologies of the IKBFU and ...
A radio telescope in the Western Australian outback has captured a spectacular new view of the center of the galaxy in which we live — the Milky Way. The image from the Murchison Widefield Array (MWA) telescope shows what our galaxy would look like if human eyes could see radio waves. The Galactic Center of the ...
Conventional wisdom tells us that large objects appear smaller as they get farther from us, but this fundamental law of classical physics is reversed when we observe the distant universe. Astrophysicists at Kent simulated the development of the biggest objects in the universe to help explain how galaxies and other cosmic bodies were formed. By looking ...
