Universe vs. Galaxy

Education, Just for Fun, Science

The Universe is far too large for most of us to comprehend. There are 3 trillion galaxies in the observable universe and it keeps expanding (as does our ability to observe).  Our galaxy is minuscule by comparison but it is still huge at 100,000 light years across. The closest neighbor to our solar system is Andromeda, only 2 ½ light years distant. It is estimated that there are between 100 and 400 billion solar systems in the Milky Way. Using the midpoint of 250 billion and the estimated number of earthlike planets per solar system at 40% (based on what we have seen so far) that puts the potential planets with life at 100 billion. If only 1% of them have life and of that number, only 1% have intelligent life that still leaves 10 million planets that could provide alien visitors. Forget the universe our galaxy has plenty of potential for intelligent life.

Astronomers have just identified a nearby solar system hosting seven Earth-sized planets. Most intriguing: Three planets that orbit its central star — known as TRAPPIST-1 — may even be within a habitable zone. That means they fall within a region that could support life as we know it. As such, these newfound worlds are good sites to focus a search for alien life.

TRAPPIST-1’s big planetary family also hints that many more cousins of Earth may exist than astronomers had thought.

“It’s rather stunning that the system has so many Earth-sized planets,” says Drake Deming. He’s an astronomer at the University of Maryland in College Park. Every stable spot where a planet could be is an Earth-sized one. And that, he adds, “bodes well for finding habitable planets.”

Astrophysicist Michaël Gillon works at the University of Liège in Belgium. He was part of a team that announced last year that they had found three Earth-sized planets around TRAPPIST-1. This dwarf star is only about the size of Jupiter.  It’s also much cooler than the sun. And it’s a relative neighbor to Earth, a mere 39 light-years away in the constellation Aquarius.

Follow-up observations with the Spitzer Space Telescope and additional telescopes on the ground now show that what first appeared to be a third planet is a quartet of Earth-sized ones. Three of these may be habitable.

If those planets have Earthlike atmospheres, their surfaces may even host oceans of liquid water. Or at least that’s what Gillon and his colleagues reported online on February 22 in Nature. Their data also offer signs of a seventh, outermost planet.

I have always been enamored by cars, especially powerful ones. Upon graduation from university, my dad promised to buy me a new vehicle if the cost did not exceed $3k. There was no doubt that it would be a 335 HP GTO with a 3-speed floor shifter. To keep the price in line I could only afford a few options. No power anything (steering, windows, etc.). I opted for Wide Oval tires and a basic radio. Turning corners took muscle power. This photo could have been my car’s 1963 twin. The 400 cubic inch engine (equivalent to 6.5 liters). It produced an amazing 52 hp per liter.

Later in life, I purchased a Mitsubishi FTO while living in New Zealand. Not considered a muscle car; nevertheless, the 2-liter V6 5-speed manual transmission produced 200 HP. At 100 HP per liter, it was almost double that of the GTO. BTW it had a top speed of 155 MPH about 25 MPH faster than the GTO.

Engine efficiency has come a long way thanks to auto racing. Consider the 2.2-liter Indy Cars that produce 800 HP, almost 400 HP per liter or the even more amazing 1.6-liter Formula 1 cars that produce 1,000 HP (over 600 HP per liter)
