A new cosmic dawn: The Webb Telescope’s first color images are arriving soon

Posted by in category: space

“We’re just human, and we cannot predict what the universe is going to tell us.”

It’s the moment we have all been waiting for: The James Webb Space Telescope will make its first scientific observations of the universe in the coming weeks. The first full-color images will drop on July 12, 2022, along with spectroscopic data.

This is the crescendo moment in a scientific symphony that has been tuning up for the last two decades.

Using laser technology to measure the rotational cooling of molecular ions colliding with electrons

Posted by in categories: particle physics, quantum physics, space

When it is free in cold space, a molecule will spontaneously cool down by slowing its rotation and losing rotational energy in quantum transitions. Physicists have shown that this rotational cooling process can be accelerated, slowed down and even inverted by the molecule’s collisions with surrounding particles.

Researchers at the Max-Planck Institute for Nuclear Physics in Germany and the Columbia Astrophysics Laboratory have recently carried out an experiment aimed at measuring the rate of quantum transitions caused by collisions between and electrons. Their findings, published in Physical Review Letters, offer the first experimental evidence of this rate, which had previously only been theoretically estimated.

“When electrons and molecular ions are present in tenuous, ionized gases, the lowest quantum level populations of the molecules can be changed in a collision process,” Ábel Kálosi, one of the researchers who carried out the study, told “One example of this process is in interstellar clouds, where observations reveal molecules predominantly in their lowest quantum states. The between the negatively charged electrons and the positively charged molecular ions makes the process of electronic collisions particularly efficient.”

James Webb Space Telescope’s first full-color images will be revealed on July 12th

Posted by in category: space

After the launched, we’ll get our first look at full-color images captured by the telescope. The European Space Agency says the imagery and first spectroscopic data on July 12th.

“The release of Webb’s first full-color images will offer a unique moment for us all to stop and marvel at a view humanity has never seen before,” Webb deputy program director Eric Smith said. “These images will be the culmination of decades of dedication, talent, and dreams — but they will also be just the beginning.”

JWST required several months of preparation before starting science work. The process included to its operating temperature, calibrating instruments and aligning the mirrors. The ESA, NASA, the Canadian Space Agency and the Space Telescope Science Institute (STSci) spent over five years figuring out what Webb should capture first in order to show off what the observatory can do.
