Evidence found of white dwarf remnant after supernova

space

An international team of space scientists has found evidence of what they believe is a remnant of a type Iax supernova—a white dwarf moving in a way that suggests it was blown across part of the universe by the power of a thermonuclear explosion. In their paper published in the

This supernova shock wave slammed into its companion star

Fast followup allowed astronomers to see the cause of the explosion. Type Ia supernovae are one of the most important tools in an astronomer’s toolkit. These bright but brief events are one of just a few reliable “standard candles” that allow us to measure not only vast distances accurately, but also

Is Dark Matter Less ‘Lumpy’ Than Predicted?

Don Lincoln is a senior scientist at the U.S. Department of Energy's Fermilab, the country's largest Large Hadron Collider research institution. He also writes about science for the public, including his recent "The Large Hadron Collider: The Extraordinary Story of the Higgs Boson and Other Things That Will Blow Your Mind" (Johns

Astronomers just mapped the inside of a supernova

It turns out these events could be even more impressive than we thought. A supernova is the largest explosion you might ever see if you ever get to see it! It’s the death of a star, and stars go out with a bang. They’re still mostly a mystery to science. It’s

Most Accurate Map of Recent Universe Unveiled by Scientists

universe

A new map of the universe has been unveiled by scientists, revealing the last seven billion years of the history of the cosmos.The results of the Dark Energy Survey show how dark matter is distributed across the galaxy. Until now, scientists used models to show where it fell. These models are

Twilight observations reveal huge storm on Neptune

Spectacular sunsets and sunrises are enough to dazzle most of us, but to astronomers, dusk and dawn are a waste of good observing time. They want a truly dark sky.Not Ned Molter, a UC Berkeley astronomy graduate student. He set out to show that some bright objects can be studied

Ancient Venus May Have Had an Ocean of Water

French scientists have run computer simulations about the formation of Venus that suggest that “Earth’s Twin” once had a thin ocean of water shortly after it formed.The researchers with the Université Paris-Saclay ran the complex simulation and published their findings in the Journal of Geophysical Research. While today Venus is a barren ball

Scientists may have found a Neptune-sized alien moon

Astronomers have found an abundance of exoplanets, but no exomoons. Despite ongoing efforts, the tiny celestial bodies have just been too elusive to detect using modern technology. However, researchers might have just hit paydirt. They've used Kepler Space Telescope data to discover signs of what looks like a Neptune-sized moon

Scientists May Have Found The First Moon Outside The Solar System

Kepler

In what would be a pretty major discovery, astronomers say they may have found the first moon beyond the Solar System – known as an exomoon.The potential discovery is 4,000 light-years away around a star called Kepler-1625. It was made using NASA’s Kepler Space Telescope by three astronomers, Alex Teachey
