A mysterious object is being dragged into the supermassive black hole at the Milky Way's center      (via sciencedaily.com) 

An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.

James Webb spots super old, massive galaxies that shouldn't exist      (via sciencedaily.com) 

A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.

Improving the performance of satellites in low Earth orbit      (via sciencedaily.com) 

On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.

The switch made from a single molecule      (via sciencedaily.com) 

Researchers have demonstrated a switch, analogous to a transistor, made from a single molecule called fullerene. By using a carefully tuned laser pulse, the researchers are able to use fullerene to switch the path of an incoming electron in a predictable way. This switching process can be three to six orders of magnitude faster than switches in microchips, depending on the laser pulses used. Fullerene switches in a network could produce a computer beyond what is possible with electronic transistors, and they could also lead to unprecedented levels of resolution in microscopic imaging devices.

Astrophysics: Scientists observe high-speed star formation      (via sciencedaily.com)     Original source 

New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed, research within the FEEDBACK programme on board the flying observatory SOFIA revealed.

Tadpole playing around black hole      (via sciencedaily.com)     Original source 

A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.

Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?      (via sciencedaily.com)     Original source 

If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. These elements are part of the atmosphere around planets and part of molecules like sugar, alcohols and simple amino acids as well. The new James Webb Space Telescope (JWST) has contributed to the discovery of different ices in a molecular cloud, 'Chameleon 1' -- one of the coldest and darkest regions to have ever been explored. Astronomers assume that these types of molecules were also present in the cold cloud of gas and dust forming our own solar system.
