No one knows where it came from

Posted by in category: alien life

No one knows how long it has been drifting through the empty, cold abyss of interstellar space. But this year an object called comet 2I/Borisov came in from the cold. It was detected falling past our Sun by a Crimean amateur astronomer. This emissary from the black unknown captured the attention of worldwide astronomers who aimed all kinds of telescopes at it to watch the comet sprout a dust tail. The far visitor is only the second known object to enter our solar system coming from elsewhere in the galaxy, based on its speed and trajectory. Like a racetrack photographer trying to capture a speeding derby horse, Hubble took a series of snapshots as the comet streaked along at 110,000 miles per hour. Hubble provided the sharpest image to date of the fleeting comet, revealing a central concentration of dust around an unseen nucleus. The comet was 260 million miles from Earth when Hubble took the photo.

In 2017, the first identified interstellar visitor, an object formally named ‘Oumuamua, swung within 24 million miles of the Sun before racing out of the solar system. Unlike comet 2I/Borisov, ‘Oumuamua still defies any simple categorization. It did not behave like a comet, and it has a variety of unusual characteristics. Comet 2I/Borisov looks a lot like the traditional comets found inside our solar system, which sublimate ices, and cast off dust as they are warmed by the Sun. The wandering comet provides invaluable clues to the chemical composition, structure, and dust characteristics of planetary building blocks presumably forged in an alien star system.

Diet Change In Old Age May Lead To Longevity: Study

Posted by in categories: food, life extension

Diet Plan For Old Age: Reduced food intake must be implemented early and be sustained.

Someone has rightly said, ‘healthy eating begins with you.’ Nourishing your body with the right nutrients and maintaining a healthy weight can help you stay active and independent even as you age. According to a recent study published in the journal Nature Metabolism, reduced intake of food in both humans and animals may improve health in their old age, further leading to longevity. However, in order to improve health in old age and to extend lifespan, the pattern of the diet (diet plan) must be established earlier in life. Scientists from the Max Planck Institute for Biology of Ageing, the Excellence Cluster for Ageing Research at the University of Cologne, the Babraham Institute in Cambridge and UCL observed that mice become healthier when they were fed in moderation from early stage and maintained it before entering old age.

Researchers discover mechanisms for the cause of the Big Bang

Posted by in categories: cosmology, engineering

The origin of the universe started with the Big Bang, but how the supernova explosion ignited has long been a mystery—until now.

In a new paper appearing today in Science magazine, researchers detailed the mechanisms that could cause the explosion, which is key for the models that scientists use to understand the origin of the universe.

“We defined the critical criteria where we can drive a flame to self-generate its own turbulence, spontaneously accelerate, and transition into detonation,” says Kareem Ahmed, an assistant professor in UCF’s Department of Mechanical and Aerospace Engineering and co-author of the study.

A new type of black hole has been discovered, astronomers say

Posted by in category: cosmology

Astronomers studying black holes in our galaxy, the Milky Way, have discovered what they believe to be a new type of black hole. This previously unknown class of black holes could be smaller than others that were previously dubbed the smallest black holes.

The researchers were creating a black hole census when they made the discovery. Their finding, in addition to sharing a novel way to search for black holes, published Thursday in the journal Science.

“We’re showing this hint that there is another population out there that we have yet to really probe in the search for black holes,” said Todd Thompson, lead study author and professor of astronomy at The Ohio State University.

Video of Amazon Prime Air’s Delivery Drone In Action

Posted by in categories: drones, entertainment

While maybe not as riveting as your favorite movie, this video published by Amazon shows it’s current version delivery drone in action. It is worth noting that the takeoff and landings are on a identified platform landing areas. It also does not show the transfer of the items from pick-up to delivery but it does give you an idea of the flight pattern of the drone and the interesting way that it handles take off and landings.
