They don’t look like our other spherical maps we’re used to seeing. So what’s actually going on? “The bedrock nature of space and time and the unification of cosmos and quantum […]
An Applicant’s Guide To NASA Astronaut Selection This guest post was written by Brian Shiro: NOAA geophysicist, NASA researcher, and co-founder of Astronauts for Hire. “I wasn’t destined to be […]
Our Sun will someday become a red giant, and then a planetary nebula + white dwarf combination. Here’s what lies between. “It will be found that those contained in one article […]
The largest asteroid in the Solar System is hiding volatile materials that have never seen the Sun. “Lots of science fiction deals with distant times and places. Intrepid prospectors in the […]
With $100 million invested towards it and an incredible concept behind it, could this be the start of interstellar travel? “Fundamental physics is like an art more or less. It’s […]
An incredible live-blog of an incredible event. “It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new […]
A live-blog event of a fabulous public lecture given by Katie Freese on the unseen components in our Universe. “If you take everything we know… it only adds up to […]
When two of the largest cosmic structures crash together, the effects show up everywhere. Everywhere, that is, but the dark matter. “It may be that ultimately the search for dark matter […]
These stars are too hot and blue for their age, and the leading theory just got a strike against it. “Youth is the gift of nature, but age is a work […]
A discovery that never would have happened with robots instead of humans. “It’s like trying to describe what you feel when you’re standing on the rim of the Grand Canyon or […]
If they change and distort spacetime as the ripples pass through, could what was once inside actually get out? “Find a place inside where there’s joy, and the joy will burn […]
Are comets and asteroids periodic, and are we due? “Biological diversity is messy. It walks, it crawls, it swims, it swoops, it buzzes. But extinction is silent, and it has no […]
How we’ll directly take pictures of Earth-like planets in the future! “We stand on a great threshold in the human history of space exploration. If life is prevalent in our neighborhood […]
Is it how the Universe began, or just how our observable Universe began? They’re not the same! “These theories were based on the hypothesis that all the matter in the universe […]
Not water, not ice, and definitely not aliens. Here’s how we know. “You are the salt of the earth. But remember that salt is useful when in association, but useless in […]
From the Milky Way’s perspective, there are hundreds of galaxies visible with even a small telescope. But from this galaxy’s location? Zero. “If the expansion of the space of the […]
And here’s the reason why, despite all you may have heard. “Thou shalt not embarrass thyself and thy colleagues by claiming false planets.” –Bill Cochran Late last year, one of the […]
I scored an exclusive interview with Dave Reitze, the executive director of LIGO. Take a trip inside his Universe. “When I was in high school, I was certain that being […]
In 30 million years, we’ll undergo star formation unlike anything else since before there were mammals on Earth. “Think about it this way — a boomerang goes out and comes back to you […]
NASA is getting really serious about its mission to land humans on Mars in the 2030s.
LIGO was just the beginning of this new field of science, but a different experiment will lead the quantum breakthrough! “If you are not completely confused by quantum mechanics, you […]
The two best-explored outer Solar System worlds orbit one another. But no one was prepared for what New Horizons saw. “Just as a Chihuahua is still a dog, these ice dwarfs […]
If we came along too soon, would we ever have discovered dark energy? “Even if I stumble on to the absolute truth of any aspect of the universe, I will not […]
From cities across the world, fireworks were the spectacular sight. But near the poles, nature was the star of the show. “You cannot rob me of free nature’s grace,You cannot […]
With, as Carl Sagan famously put it, “billions and billions” of stars out there, many of them with planets that would support life, why aren’t we seeing that life the form of visits from aliens?
Ice mountains, frozen nitrogen flats and surprisingly familiar features show what the outermost worlds looks like. “We’ve learned that the view of four inner rocky planets and four outer gas giants […]
