We May Soon Look Back in Time at the First Supergiant Stars in the Universe

We need to talk about the dark ages. No, not those dark ages after the fall of the western Roman Empire. The cosmological dark ages. The time in our universe, billions of years ago, before the formation of the first stars. And we need to talk about the cosmic dawn: the birth of those first stars, a tumultuous epoch that completely reshaped the face the cosmos into its modern form.Those first stars may have been completely unlike anything we see in the present universe. And we may, if we’re lucky, be on the cusp of seeing them for the first time.

The 10 Greatest Scientific Achievements of 2018

December is the month of best-of lists, which is always a challenge — especially when you’re ranking the most influential scientific achievements of the year. Who’s to say a discovery of an ancient fossil is any better than the development of a new drug? Or that landing on an asteroid is any better than discovering spider milk? Alas, you have to draw the line somewhere, and here’s where we drew ours. Check out our list of the top 10 greatest scientific achievements of 2018 below.

2018 in review from a science perspective

Worried You’re Dating a Psychopath? These Are the Signs to Look For

It may sound like a scene straight out of a horror movie, but statistically, you’re not that unlikely to end up on a date with a psychopath. It’s estimated that about 1 in 100 people are psychopaths — similar to the number of people who are teachers.And while we may associate psychopaths with horrifying criminals such as the American serial killer, rapist, and necrophile Ted Bundy, the majority of psychopaths aren’t actually criminals, but live fairly ordinary lives in our midst. So how do you know if you happen to be dating a psychopath and what should you expect? Luckily, there’s research on the topic.

Physicists Have Developed a Ridiculously Accurate Atomic Clock

Physicists have developed an atomic clock so accurate that it would be off by less than a single second in 14 billion years. That kind of accuracy and precision makes it more than just a timepiece. It’s a powerful scientific instrument that could measure gravitational waves, take the measure of the Earth’s gravitational shape, and maybe even detect dark matter.How did they do it?

Micrometeorites Are Tiny Space Debris that Pose a Big Problem

If there’s one thing that decades of operating in Low Earth Orbit (LEO) has taught us, it is that space is full of hazards. In addition to solar flares and cosmic radiation, one of the greatest dangers comes from space debris. While the largest bits of junk (which measure more than 10 cm in diameter) are certainly a threat, the real concern is the more than 166 million objects that range in size from 1 millimeter to 1 centimeter in diameter.

This Is What the Entire Known Universe Looks Like in a Single Image

The farthest manmade thing from Earth is Voyager 1. Though this 1970s-era spacecraft is pretty far out there by now and still sending back information, it’ll never be able to take a snapshot of the Solar System. Or the Milky Way. And definitely not the entire observable universe. But with a little math and artistic prowess, we can cobble together what we may look like from way, way, way out there.
