Have you ever wondered how the first stars and galaxies formed in the early universe? How did they change the universe forever, and what can they tell us about its history and age? Well, you are in for a treat, because in this video, we will explore the amazing discovery of Maisie’s galaxy, one of the oldest and most distant galaxies ever observed. We will also learn how this galaxy challenges our current view of the universe and its age, and how it sheds light on the epoch of reionization, when the first stars and galaxies ionized the hydrogen gas in the early universe.

A never-before-seen meteor shower may illuminate the heavens with an uncountable number of bright streaks on Monday night into Tuesday early. Those are the best predictions meteorologists have for the Tau Herculids, a prospective celestial event that has sky-watching fans excited. Meteor showers can happen when the Earth plows into debris produced by a comet (or, occasionally, asteroids). The source of the Tau Herculids is Comet 73P/Schwassmann-Wachmann 3, or SW3 for short. Discovered in 1930, the trifling ice ball originally clocked in at about two-thirds of a mile in diameter, so it rarely produced enough material to generate major nighttime fireworks. But in 1995, SW3 crumbled, producing a large fragment field that our planet is about to encounter. If the Tau Herculids occur, they will be best visible in the lower 48 United States on Monday, May 30, and early Tuesday, May 31, presumably about 1 a.m. Eastern time. The nicer the view, the further south you dwell. Skywatchers in West Africa, the Caribbean, and South America are also in for a treat. Those living in high latitudes, such as Alaska, are out of luck. To catch the shower, get away from bright city lights and find the darkest and clearest location you can, one with few hills or other obstacles on the horizon. The moon will be new that night, so its light will not interfere with the display. Allow about half an hour for your eyes to adjust to the darkness. Unlike meteor showers that are visible for days before and after a peak night, this show will not last long, if it occurs at all. NASA models are pessimistic, implying that few if any, meteors will be observable. However, Mr Joe Rao, "an associate astronomer at the Hayden Planetarium in New York," cites predictions from credible meteor watchers on the other end of the spectrum who expect to witness 10,000 to 100,000 meteors each hour. If these predictions are correct, the Tau Hercules will be a meteor shower, potentially the LARGEST IN RECORDED HISTORY. However; Much will depend on the size and the speed of the debris as it hits the atmosphere and how big the comet’s leftover particles are. If the fragments are on the smaller side, they may produce many slow streaks that are too dim for the human eye to see. Night sky devotees have been burned before when announcing possible wonders like the supposedly once-in-a-lifetime sighting of Comet Kohoutek in 2020 that failed to live up to expectations
