In 2023, the NASA OSIRIS-REx mission returned a sample of dust and rocks collected on the near-Earth asteroid Bennu. In addition to the information about the universe gleaned from the sample itself, the data generated by ...
We've known the universe is expanding for a long time. The first solid paper demonstrating cosmic expansion was published by Edwin Hubble in 1929, based on observations made by Vesto Slipher, Milton Humason, and Henrietta ...
The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include discovering the earliest ...
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know ...
This week, biologists tracked down a mysterious group of orcas near Chile; Hubble spotted a black hole jet that causes stars along its trajectory to erupt; and researchers explained mysterious craters that began appearing ...
A new study has mapped out the gravitational basins of attraction in the local universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. The study has been published in ...
Given how unfathomably large the universe is, it is perhaps understandable that we haven't yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we could explain, that cosmologists ...
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time ...
A Doppler shift is defined as a change of frequency of light or sound when an object is moving toward or away from an observer. Edwin Hubble observed in 1929 that galaxies appear on average to be moving away from us (see ...
An unexpected finding about how our universe formed is again raising the question: do we need new physics? The answer could fundamentally change what physics students are taught in classes around the world.
