For the first time, scientists have managed to find our solar system's precise center of gravity down to about 100 meters — a flabbergastingly precise measurement on the scale of our vast solar system.
It sounds like a trivial feat — think back to the posters hanging in your classroom and you might reasonably assume that the center of our solar system is smack dab in the middle of the Sun. But finding the gravitational center — its barycenter, in the lingo — is actually a complex task, ScienceAlert reports , that involves factoring in the pull of every planet, asteroid, and moon in the star system.
Many things are taking place:
Astronomers Have Located The Centre of The Solar System to Within 100 Metres
When you picture the Solar System in your head, most people would think of the Sun, stolid and stationary in the centre, with everything else whizzing about around it. But every body in the Solar System also exerts its own gravitational tug on the star, causing it to move around just a tiny bit.
Therefore, the precise gravitational centre (or barycentre) of the Solar System is not smack-bang in the middle of the Sun, but somewhere closer to its surface, just outside it. But it hasn't been easy for us to figure out exactly where this barycentre is, due to the myriad gravitational influences at play.
Exposed planetary core spotted circling distant star | Space
Astronomers have spotted the exposed core of a massive alien world , an unprecedented find that could shed considerable light on planet formation, evolution and diversity.
The planetary core, called TOI-849b, is unlike anything scientists have seen before, and it could hide a wealth of exciting information in its bizarre depths, researchers say.
"There is a huge range and diversity of planets out there, with more found every week, and if anything is becoming clear it is that we should not be surprised at strange new discoveries," said Armstrong, a researcher in the physics department at the University of Warwick in England. "With luck, the new understanding of planet formation planets like TOI-849b can open up will help us understand how our own solar system formed."

How we can explore the cosmos by letting it come to us | Astronomy.com
Let's face it, we're not going anywhere, at least not anytime soon. Anyone who grew up on a diet of science fiction—often Star Trek or Star Wars of one generation or another—has at some point felt the longing for actual, real-world interstellar travel. Then come the hard doses of adult reality.
We have no remotely plausible technology that could transport humans to planets around other stars. We don't even the technology to send a tiny robotic spacecraft to another star system in a timely manner. (People are thinking about it , but even the proof-of-concept experiments have not yet begun; first test flights are probably decades away at minimum.) Hell, with COVID-19 still raging, many of us are barely making it out of our homes right now.
NASA Just Released a Spectacular 10-Year Timelapse of Our Mesmerising Sun
For once, we're going to break with the usual advice and tell you that you very much should stare into the Sun. Specifically, into NASA's new 10-year timelapse video of activity on the solar surface.
Lasting 61 minutes in total, the awe-inspiring video has been produced from high-resolution imagery captured by the Solar Dynamics Observatory (SDO) spacecraft over the last decade. Each second on the video represents a day at the centre of the Solar System.
WoodMac: Solar and Storage Prices Falling Faster Than Expected Due to COVID-19 | Greentech Media
The fallout from the coronavirus pandemic and the looming threat of recession are expected to drive down pricing for front-of-the-meter solar and storage systems even faster than expected. Project construction delays and tightening consumer spending will drive down storage and electric vehicle demand, according to Wood Mackenzie. This in turn will cause U.S. front-of-the-meter (FTM) storage system costs to decline more rapidly than previously forecast.
The Real Center of Gravity of the Solar System was Calculated - Somag News
Scientists have identified the true center of gravity of the Solar System. Accordingly, the center of gravity of the Solar System is located on the surface of the Sun, not the core.
Have you ever thought where the center of gravity of our Solar System is? Most of you will probably say that the center is the middle of the Sun, that is, the nucleus. However, this is not true. Because, contrary to what we think, the Sun does not stand in a fixed position while rotating around its own axis. All the planets, especially Jupiter, the largest planet in the Solar System, have a slight attraction force on the Sun. Therefore, the Sun shows an oscillation as it revolves around
