An article on the study titled “An interstellar origin for high-inclination Centaurs” is published in the Royal Astronomical Society’s Monthly Notices . The study was supported by FAPESP.
“The Solar System formed 4.5 billion years ago in a stellar nursery, with its systems of planets and asteroids. The stars were close enough to each other to foster strong gravitational interactions that led to an exchange of material among the systems. Some objects now in the Solar System must therefore have formed around other stars. Until recently, however, we couldn’t distinguish between captured interstellar objects and objects that formed around the Sun.

Astronomers Develop Method to Detect Tiny Black Holes in Outskirts of Our Solar System |
Amir Siraj and Professor Avi Loeb from the Department of Astronomy at Harvard University have developed a new method to search for primordial black holes in the outer Solar System, based on accretion flares that result from impacts of small bodies from the Oort Cloud .
Siraj & Loeb explore the possibility that accretion flares resulting from the tidal disruption of small Oort Cloud bodies by a putative primordial black hole could power an observable optical signal that could be searched for with the upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time. Image credit: Sci-News.com / Zdeněk Bardon / ESO.
Colonizing our solar system will make our species very hard to eliminate

Our expansion into the galaxy will begin slowly, for the stars are immensely distant. Scatter 200 billion grains of salt – each representing a single star – into an approximation of the Milky Way and, in our neighbourhood, each grain of salt would be seven miles from its nearest counterpart. To reach Alpha Centauri, the triple-star system closest to our own, with a human crew we need to travel at least at 10% of lightspeed (about 30,000 kilometres per second), making for a four-decade

Pinning down the sun's birthplace just got more complicated | Science News
To nail down a stellar birthplace, astronomers have considered the solar system's chemistry, its shape and many other factors. Most astronomers who study the sun's birthplace think the gentle, large association scenario is most likely, says astrophysicist Fred Adams of the University of Michigan in Ann Arbor, who was not involved in the new work.
But most previous studies didn't include stars' motions over time. So astrophysicists Susanne Pfalzner and Kirsten Vincke, both of the Max Planck Institute for Radio Astronomy in Bonn, Germany, ran thousands of computer simulations to see how often different kinds of young stellar families produce solar systems like ours.
Black hole the size of a grapefruit lurking at the edges of our solar system 'could be Planet X'-
Scientists are now trying to figure out if a grapefruit-sized blackhole actually lurks at the fringes of our outer solar system.
In the last few years, researchers have noticed an odd clustering of multiple trans-Neptunian objects (TNOs), which are found in the far outer solar system.
According to a report by Space.com , some scientists believe that the TNOs' paths have been sculpted by the gravitational pull of a big object which is five to 10 times bigger than the Earth.
The magic behind solar power | AZ Big Media
While most people know the cost and environmental benefits of solar power, few know how they actually work. The magic behind this sun-to-energy conversion is much more straightforward than one might think.
To really understand the science behind solar panels it is necessary to break down the two different types:
* * *
Photovoltaic systems are composed of a number of cells, which are made of semiconductors, such as silicon, which absorb direct sunlight generating direct current (DC) energy. Inverter technology then converts DC energy into useable alternating current (AC) energy, which then flows through a home's electrical panel and is distributed appropriately.
