But what if scientists discover that Earth is threatened by an entire asteroid shower? Or that some other cosmic phenomenon, such as nearby star going supernova, is on track to destroy the planet?
In those instances, our survival might depend not on stopping the destructive event, but on getting the hell out of its way — and now, an astrophysicist has designed a stellar engine that could theoretically move Earth's entire solar system from one part of the Milky Way to another.
Not to change the topic here:
Astrophysicist Describes A Stellar Engine That Can Move The Solar System - Science
Interstellar exploration is a significant part of space exploration that will reveal the secrets of the cosmos. Adding to it, human travel to interstellar space would be an history-making event as it would present countless possibilities. While the spaceships to allow such visits don't exist yet, there might be no need for them. An astrophysicist has envisioned the use of a 'stellar engine' that will turn our solar system into a spaceship!

That mix of incentives has led to a surge in interest among homeowners who want to add solar arrays and batteries to their homes, and the companies offering those packages have noticed. Sunrun, which sells solar panels primarily through long-term lease agreements, in October saw traffic spike 1500% to the page on its website which explains how to power through blackouts, shortly after Pacific Gas & Electric cut power proactively to thousands of people hoping to prevent wildfires.
"Interest has by far gone through the roof,” said Evelyn Huang, chief customer experience officer at Sunrun.

Many things are taking place:
Scientists Have Calculated How Long It'll Take to Reach Distant Stars
A team of scientists—Coryn Bailer-Jones of the Max Planck Institute for Astronomy in Switzerland and Davide Farnocchia of NASA’s Jet Propulsion Laboratory—have done the calculations. Essentially, the pair found a way to chart how long it would take a spacecraft to get from our humble solar system to the next system over, according to a paper uploaded to the pre-print server arXiv.
Using this data and data about the projected paths of both the voyager spacecrafts as well as Pioneer 10 and 11, which are careening toward the outer reaches of the solar system, the researchers were able to create a timeline of when these crafts might reach distant star systems. For those eager to visit other worlds, brace for some bad news.
'A nice Christmas comet': A new interstellar object has entered our solar system |
On August 30, Gennady Borisov, an astronomer with the Crimean Astrophysical Observatory spotted an interstellar object coming into our solar system. Shortly after its discovery, NASA’s scout system noted that the object’s orbit was highly unusual compared to its predecessor, Oumuaamua.
When Oumuamua was discovered back in 2017, it opened the door to new information about how interstellar objects travel through the solar system on a regular basis. Unlike Oumuamua though, this second deep space object will be much more trackable, and for a longer period of time.
An incredible animation by a planetary scientist shows how fast each planet spins by putting them
A video by planetary scientist James O'Donoghue shows a slice of every planet in the solar system spinning on one giant globe. The animation provides a comparison of how quickly (or slowly) each planet rotates. Jupiter's Great Red Spot zips around 2.4 times faster than Earth, while Venus spins so slowly you can't tell it's moving backwards. Visit Business Insider's homepage for more stories.
James O'Donoghue, a planetary scientist at the Japanese space agency (JAXA) and formerly at NASA , spends his free time making animations of space concepts like the history of the moon and the vastness of our solar system .

In four papers published Dec. 4 in Nature, researchers describe strange space phenomena and a flood of new data that will help us understand everything from the nature of stars to improving our forecasting of solar storms that can affect electronics on Earth.

It could push the Sun at a speed of about 50 light years per one million years. https://t.co/1nwZjblfDx futurism (from Brooklyn, NY) Mon Dec 30 20:16:03 +0000 2019
