To Catch a Dancing Star: The Story of ‘Extreme Precision’ Spectroscopy

Posted by in category: space

Dr. Arpita Roy, Space Telescope Science Institute.

It has been three decades since astronomers first discovered planets outside our solar system. This profound scientific moment established the field of exoplanet science and has led us on a whirlwind tour of other worlds, none of which (so far) have been quite like our own.

Humanity Could Survive A ’Planet-Killer’ Asteroid, A New Study Says

Posted by in categories: asteroid/comet impacts, existential risks, physics

About 66 million years ago, a “planet killer” — a 10-kilometer-wide rocky asteroid — hit Earth. The Chicxulub impact caused a mass extinction on a planetary scale, killing off an estimated 76 percent of all species living on Earth at the time, including the dinosaurs. According to a study published by Philip Lubin and Alexander N. Cohen, both physicists at the University of California in Santa Barbara, there is a chance that humanity could survive such a similar impact happening in the near future.

There currently are about 1,200 asteroids on a publicly available asteroid risk list, but all are smaller than one kilometer. The probability of a Chicxulub sized asteroid (5 to 15 kilometers across) hitting Earth is once in a billion years — very low, but not impossible.

Artificial intelligence system rapidly predicts how two proteins will attach

The machine-learning model could help scientists speed the development of new medicines.

This technique could help scientists better understand some biological processes that involve protein interactions, like DNA replication and repair; it could also speed up the process of developing new medicines.

“Deep learning is very good at capturing interactions between different proteins that are otherwise difficult for chemists or biologists to write experimentally. Some of these interactions are very complicated, and people haven’t found good ways to express them. This deep-learning model can learn these types of interactions from data,” says Octavian-Eugen Ganea, a postdoc in the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) and co-lead author of the paper.

Here’s Everything You Need to Know About the Life Cycle of Stars

Posted by in category: nuclear energy

Stars are giant balls of gas that emit light and heat. They are mostly made up of hydrogen and helium gases and can have huge masses. For instance, the heaviest star yet found in our universe, called R136a1, has a mass of around 315 times that of our Sun and is almost 9 million times more luminous.

Stars are so heavy that they should collapse due to the inward force of gravity exerted by their own weight but thanks to the nuclear fusion reactions taking place in their cores, the massive inward gravitational force is balanced by the strong heat and pressures found within a star. This balance between gravity and gas pressure from energy generation is called hydrostatic equilibrium, and it is both self-regulating and finely tuned. goes up must come down, as the saying goes, but what is gravity?
