NASA has announced the launch of the James Webb Telescope has been delayed to 2019. The space agency said the reason for the postponement was not the result of any technical concerns, but that integrating all the elements of the spacecraft was “taking longer than expected.”Initially, NASA said it was
Several of the planets orbiting a nearby star may harbor “substantial amounts” of water, astronomers say, including three planets situated in a habitable part of the star’s solar system.The star—called TRAPPIST-1—is an ultracool dwarf star 40 light years away. It is orbited by seven Earth-size planets, according to the
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
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
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
The hype over the Great American Eclipse on 21 August is certainly reaching fever pitch now that we're less than ten days out, and we hope that you are already prepared.But where there's hype, there's also conspiracy theories. Like the one that's been gracing tabloid headlines all week - that
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
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
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
Thanks again, Hubble.
For the first time, scientists have detected water molecules "glowing" around a planet outside our Solar System, giving us the best evidence yet of an exoplanet with a stratosphere.It's a huge find, and one that could tell us a lot more about the science of Hot Jupiters –
The beginning of new solar physics.
The innermost region of the Sun is hidden from our eyes, and it looks like this stealth has enabled the core to conceal a massive secret.For the first time, scientists have been able to accurately measure the rotation of the solar core, revealing that it
Our Solar System is littered with chunks of space rocks that whizz around in different orbits and varying speeds – and it’s no big deal until one of those rocks turns out to be on a nasty unexpected trajectory and smashes into Earth.It’s actually a pretty unlikely apocalypse scenario, but
