Quasar J0529-4351:
Consuming just over one Sun's worth of matter each and every day, it is the fastest growing black hole detected so far. Also, the intense amount of energy it emits in the process of eating all that matter makes it the brightest quasar ever seen. And since quasars are already the brightest objects in the universe, this is also the most luminous known object in the universe. It's 500 trillion times brighter than our Sun and 17 billion times its mass. Located 12 billion light year away. |

Did you know?
Over the course of Earth’s history, its rotation has been slowing down. Some 1.4 billion years ago, a day lasted 18 hours and 41 minutes and during the Age of Dinosaurs, a day was only 23 hours. That’s a pretty slow-going process—so slow, in fact, that an Earth day is only 0.047 seconds longer than it was at the end of the Bronze Age. |

We are all looking forward to Monday to witness a fairly rare event. Here are some Historical, Scientific and Mythology background information to keep us enlightened.

The Lyrid meteor shower peaking this week-end.
On the night of April 14, as Earth travelled along its orbit around the Sun, the planet slipped into a fast-moving stream of icy debris left behind by an ancient comet known as C/1861 G1 (Thatcher). As these bits of comet debris began plunging into the atmosphere, they produced streaks of light in the sky and marked the beginning of the annual Lyrid meteor shower. The Lyrids typically start off fairly quiet, with only a handful of meteors streaming out of the constellation Lyra each night for the first week of the meteor shower. However, on the night of April 21-22 we pass through the densest part of comet Thatcher's debris stream. That is when the Lyrid meteor shower reaches its peak, producing around 20 meteors per hour throughout the night. |

This composite image of the Tycho supernova remnant combines X-ray and infrared observations obtained with NASA's Chandra X-ray Observatory and Spitzer Space Telescope, respectively, and the Calar Alto observatory, Spain. It shows the scene more than four centuries after the brilliant star explosion.

The Galactic Center of our Milky Way is about 25000 light years aways. A long journey.

150,000,000,000 years to get there. That's 150 Billion years. Space travel is hard. Just sayin' Edit: See post #130. This is all wrong Last edited by snowbimmer; 05-28-2024 at 03:49 PM.. |

Hopefully you remembered to turn the landing radar power switch on before blastoff, unlike Intuitive Machines' recent moon lander oopsie.....

Not to bust your chops but math is hard too. Yes, it would take a long time at 1 million miles per hour, but your 150 Billion years is 219 million times longer than it would actually take. It would only take 685 years. Still, a very long time. All those zeros and it gets confusing. I wouldn't be surprised if my response is incorrect in some way or another. |

25,000 x 6,000,000,000,000 = 150,000,000,000,000,000 miles. I stopped at hours - not sure why. So, it's 17,123,288 years. Shit....what a mess. You goofed by only going 1 light year. Your answer times 25,000 is 17,125,000. How does that sound? See? Math IS hard. I just entered zeros into the calculator - it stopped counting at a billion, but I just kept punching zeros in that the calculator was not taking. Works much better when using scientific notation. These are really big numbers. As a side note, Voyager 1 is travelling at 38,000 miles/hr. It would travel 18,000 years just to reach 1 light year. It would take 450,000,000 years to reach the galactic center. It was launched 47 years ago and is only out 15 billion miles so far - 0.25% of a light year.

Yup. I just did one light year. My steel trap mind is now closer to silly putty. I haven't been called a big schmo in a long time. Made my day! |
