The Younger Dryas Impact Hypothesis (YDIH) proposes that a cometary or meteoric body exploded over the North American area sometime around 12,900-years-ago.
In a study of the Earth’s mantle, scientists have identified two compositionally distinct continent-sized anomalies which could be traces of a protoplanet which impacted with Earth during its early formation.
The further we move away from a heat source, the cooler the air gets. Bizarrely, the same can’t be said for the Sun, but University of Otago scientists may have just explained a key part of why.
Researchers from the University of Turku, Finland, found that the axis of rotation of a black hole in a binary system is tilted more than 40 degrees relative to the axis of stellar orbit. The finding challenges current theoretical models of black hole formation.
Scientists from the University of Cambridge and the Ecole normale supérieure de Lyon, have proposed a new model of crystallisation where crystals remained suspended in liquid magma over hundreds of millions of years as the lunar ‘slush’ froze and solidified.
Groundbreaking study confirms time of year when asteroid wiped out dinosaurs and 75 percent of life on Earth.
A groundbreaking study led by researchers at...
A research group led by Kosuke Namekata and Hiroyuki Maehara at the National Astronomical Observatory of Japan (NAOJ) has been monitoring EK Draconis, a young solar-type star located 111 light-years away in the constellation Draco, the Dragon.
Impact craters are caused when the planet is struck by solid objects travelling at high velocity, producing shock waves and the compression of material to form a circular crater.
In an out of this world study, space archaeologists are reconstructing life on the International Space Station (ISS) over the past two decades, to better understand space culture and get an inside look at how astronauts interact with their tools and colleagues when above Earth.
A 4.6-billion-year-old meteorite found in a field in Gloucestershire, England, is likely a remnant of cosmic debris left over from the birth of the solar system and could answer questions about how life began on Earth.
New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy.
Astronomers have found two close pairs of quasars in the distant Universe. Follow-up observations with Gemini North spectroscopically resolved one of the distant quasar pairs, after their discovery with the Hubble Space Telescope and Gaia spacecraft.
A newly discovered planet could be our best chance yet of studying rocky planet atmospheres outside the solar system, a new international study involving UNSW Sydney shows.
Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.
