Something is ticking near the Milky Way's supermassive black hole

  • No comments
A sensitive radio survey by Breakthrough Listen has identified a candidate millisecond pulsar near Sagittarius A*, the supermassive black hole at the center of the galaxy. If confirmed, the finding could enable unprecedented tests of general relativity.

Football tackles cause severe damage to the area of ​​the brain essential for cognition

A new imaging technique developed at Columbia University has identified areas of the cerebral cortex – just behind the forehead – that are most severely damaged by repeated impacts from hitting a ball, a well-known phenomenon in hitters.

What does Trump want from universities?

  • One response
Trump is demanding the appointment of conservatives to various positions to balance what he calls the leftist bias in academia. But that's not enough for him, and he's demanding that research directions be determined and research budgets be kept.

Exposing the Myth of "Environmental Self-Destruction": The True Story of Easter Island

  • One response
Recent studies disprove the long-held belief of ecological collapse on Easter Island, and show that the population has remained stable through effective resource management over a long period of time.

A huge donation worth a billion shekels to Bar-Ilan University: one of the largest donations given to universities in Israel

The donor, who chose to remain anonymous, is a Jew from North America and a graduate of Columbia University who participated in World War II, saw the State of Israel as a safe home for the Jewish people and recognized the importance of its economic and social stability

The idea of ​​capturing carbon dioxide or converting it to other substances in order to combat climate change is not new. However, simply storing carbon dioxide in a certain compound may lead to its leakage into the environment
long image captionThis is part of the Evolution of the Universe Early Science Survey (CEERS), consisting of several near-infrared points from the NIRCam (Near Infrared Camera) camera on the James Webb Space Telescope. These observations are being made in the same region studied by the Hubble Space Telescope, known as the Extended Groth Belt. Arrows showing the directions north and east show the direction of the image in the sky. It should be noted that the relationship between north and east in the sky (as seen from below) is reversed compared to the half directions on the map of the earth (as seen from above). The image shows invisible near-infrared wavelengths converted to visible colors. The color key shows which NIRCam filters were used to collect the light. The name color of each filter is the visible color that represents the infrared light passing through that filter. The barrel ruler is marked with arc-seconds which are a measure of angular distance in the sky. One arc-second is equal to an angular measurement of 1/3600 of one degree. There are 60 arc-minutes in a degree and 60 arc-seconds in an arc-minute. (The full moon has an angular diameter of about 30 arc-minutes.) The actual size of an object that covers one arc-second in the sky depends on its distance from the telescope.

The first galaxies were much less developed than the spiral and spherical galaxies that exist today, which are actually the result of mergers, both because of the stage of development but also because of the conditions that prevailed at the time
