It doesn’t matter what you’re reading, as long as you’re reading.
We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]
Sometimes the best way to make changes is when you’re in the middle of a challenging time.
Couples that handle sexual rejection well can improve their relationship, but persistent or hostile patterns of rejection are never healthy.
The dream of an ‘Earth-like’ planet showcases our astrobiological ignorance. Over the past decade, our understanding of what planets exist around stars other than our own has exploded. The number […]
Despite the claims of one of Earth’s newest Nobel Laureates, the data doesn’t lie. One of the greatest scientific successes of the past century was the theory of the hot Big […]
One look at the uncertainties and the assumptions changes the story tremendously. Is there intelligent life out there in the Milky Way beyond our own Solar System? If so, how […]
A black hole punched a hole 15 Milky Ways across in a galaxy cluster’s gas, by far the largest ‘kaboom’ ever seen. The Universe, everywhere we look, is full of cataclysmic […]
A new study finds that factors influencing where you’re born continue to affect your earnings throughout life.
One of NASA’s original great observatories, Spitzer showed us the infrared Universe as never before. On January 30, 2020, NASA’s Spitzer Space Telescope was retired after a 17 year mission. Prior […]
After 13.8 billion years, there’s still a whole lot that’s changing as time goes on. With each new year that comes upon us, there are a slew of new events awaiting […]
Countless top-down reforms haven’t improved the U.S. education system; can community-based education make a difference?
The origin of the 3rd element on the periodic table was one of the great cosmic mysteries. We just solved it. How did we form the elements that pervade the Universe […]
Think they all burn through their fuel, die, and leave white dwarfs, neutron stars, or black holes behind? Think again. The day will come when our Sun, like most stars, can […]
The new system could soon greatly improve foreign-language interactions.
Hubble has been operational for nearly 30 years, and still produces the most spectacular images of all. Here are this year’s best. Hubble, astronomy’s revolutionary observatory, narrowly survived last year’s gyroscope […]
How does one supernova get so bright, so energetic, and so massive? It’s a spectacular mystery to solve. On February 22, 2016, one of humanity’s automated sky-scanning telescopes — the Pan-STARRS Survey for […]
Maps show the oldest company in (nearly) every country – and a few interesting corporate trends.
At the core of the largest star-forming region of the Local Group sits the biggest star we know of. Mass is the single most important astronomical property in determining the lives […]
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
The shape of our Universe has long been recognized to be flat. But that isn’t the only possibility. The Universe is expanding, and goes on for farther than even our […]
It’s a supergiant star in the final stage of its life, and it just dimmed by an enormous amount. What’s going on? When you take a look at the stars in […]
If fair treatment for all is something that’s important to you, here’s how you can help level an uneven playing field. In some ways, it’s true that life isn’t fair for […]
All supernovae are not created equal. After a 14 year investigation, the brightest ones have a surprising explanation. In 2006, astronomers witnessed a supernova that defied conventional explanation. Typically, supernovae […]
If we could see in three dimensions instead of two, we’d never have thought otherwise. Perhaps the most famous sight of a dying star is the Ring Nebula, discovered in […]
In the mid-20th century, ‘physical cosmology’ was considered an oxymoronic joke. Today, it’s Nobel-winning science. Imagine you wanted to know everything you could about the Universe. You’d want to find […]
With a new data run coming in 2019 at unprecedented sensitivity, we might finally get our answers. Over the past three years, LIGO discovered ten independent instances of merging black holes […]
