Hubble Space Telescope Captures a Spectacular Star-Studded Skyfield




The center of the globular cluster NGC 6638 in the constellation Sagittarius is seen in this breathtaking photograph filled with stars. This star-strewn image, which was captured by the NASA/ESA Hubble Space Telescope, illustrates the stellar density in the center of globular clusters, which are stable, closely bonded groups of tens of thousands to millions of stars. The data in this image was collected by Hubble using the Wide Field Camera 3 and the Advanced Camera for Surveys, two of its state-of-the-art astronomy equipment.

Hubble revolutionized the study of globular clusters since it is nearly difficult to discern the stars in them using ground-based telescopes. Since Hubble is in low Earth orbit, the Earth's atmosphere is no longer a factor in the blurring that makes it hard to distinguish one star from another. As a result, Hubble has been used to study the composition, evolution, and function of gravity in these dense systems of globular clusters.

With the NASA/ESA/CSA James Webb Space Telescope, we can now look into globular clusters that are now hidden by dust, advancing our understanding of globular clusters. Infrared wavelengths, which are less impacted by the gas and dust around young stars, are where Webb will conduct most of his observations. By examining recently created star clusters, astronomers will be able to get knowledge about stellar populations before they have a chance to develop.

A robot learns to imagine itself

Image
Our body image is not always correct or realistic, as every athlete or fashion-conscious person is aware, but it's a crucial piece of knowledge that affects how we behave in the outside world. Your brain continually plans ahead while you dress or play ball so that you may move your body without bumping, stumbling, or falling. As babies, we develop our ideal body types, and robots are doing the same. Today, a team from Columbia Engineering said that they had developed a robot that, for the first time, could learn a model of its whole body from scratch without the aid of humans. The researchers explain how their robot built a kinematic model of itself and utilized that model to plan movements, accomplish goals, and avoid obstacles in a range of scenarios in a new report published in Science Robotics. Even damage to its body was automatically detected, repaired, and then detected again. Robot looks at itself as if it were a baby discovering itself in a room full with mirrors. A roboti...

No evidence that depression is caused by low serotonin levels, finds comprehensive review

Image
According to a comprehensive analysis of previous studies undertaken by UCL experts, there is still no conclusive proof that serotonin levels or serotonin activity are the cause of depression after decades of research. The new umbrella review, which provides a summary of previous meta-analyses and systematic reviews, was just published in Molecular Psychiatry. It questions the effects of antidepressants and contends that depression is not likely the result of a chemical imbalance. Selective serotonin reuptake inhibitors (SSRIs), which make up the majority of antidepressants, were once believed to function by restoring unusually low serotonin levels. No other recognized chemical mechanism exists for how antidepressants influence the signs and symptoms of depression. "It is always difficult to prove a negative, but I think we can safely say that after a vast amount of research conducted over several decades, there is no convincing evidence that depression is caused by serotonin abno...
