Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

The current military action against Iran is a clash of ethical impulses: the security of the country versus the kind of ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right ...

Reports on March 4, 2026, revealed that a U.S. Navy submarine sank the Iranian warship IRIS Dena using a torpedo in the Indian Ocean near Sri Lanka. A torpedo is a powerful underwater missile used in ...

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

Using gravitational waves as a measure of the universe's rate of expansion could solve the biggest headache in physics, the so-called "Hubble tension." ...

A subtle gravitational-wave “hum” from merging black holes may help settle the cosmic fight over how fast the universe is ...

Until now, Tallinn assigned children to neighborhood schools based on straight-line distance from home, but this year it will use actual walking distance instead.
