NASA Astronomy Picture of the Day:

This surprising sky has almost everything. First, slanting down from the upper left and far in the distance is the central band of our Milky Way Galaxy. More modestly, slanting down from the upper right and high in Earth's atmosphere is a bright meteor. The dim band of light across the central diagonal is zodiacal light: sunlight reflected from dust in the inner Solar System. The green glow on the far right is aurora high in Earth's atmosphere. The bright zigzagging bright line near the bottom is just a light that was held by the scene-planning astrophotographer. This "almost everything" sky was captured over rocks on Castle Hill, New Zealand late last month. The featured finished frame is a combination of 10 exposures all taken with the same camera and from the same location. But what about the astrophotographer himself? He's pictured too -- can you find him? Jigsaw Fun: Astronomy Puzzle of the Day

Hannah Arendt ( 1906 - 1975 ) German-American historian and philosopher. She was one of the most influential political theorists of the 20th century. Her works cover a broad range of topics, but she is best known for those dealing with the nature of power and evil, as well as politics, direct democracy, authority, and totalitarianism. She is commemorated by institutions and journals devoted to her thinking, the Hannah Arendt Prize for political thinking, and on stamps, street names, and schools, amongst other things.

NASA Astronomy Picture of the Day:

What's different about this Moon? It's the terminators. In the featured image, you can't directly see any terminator -- the line that divides the light of day from the dark of night. That's because the featured image is a digital composite of many near-terminator lunar strips over a full Moon. Terminator regions show the longest and most prominent shadows -- shadows which, by their contrast and length, allow a flat photograph to appear three-dimensional. The overlay images were taken over two weeks in early April. Many of the Moon's craters stand out because of the shadows they all cast to the right. The image shows in graphic detail that the darker regions known as maria are not just darker than the rest of the Moon -- they are also flatter.

Earth Day is an annual event celebrated on April 22 since 1970. It is a time to demonstrate support for environmental protection and an important reminder that we all have a role to play in protecting the planet. Earth Day 2025 theme  is "Our Power, Our Planet". Here are simple things we can all do to invest in our planet:
Recycle - Pick up litter - Reuse single use plastic items - Plant a tree - Build a birdhouse / bird feeder. Learn more about this year's theme and get more tips

Credit for the Earth Day idea goes to Gaylord Nelson, an American politician from Wisconsin and leading figure in the fight against environmental degradation and social injustice. Rachel Carson, a marine biologist and best-selling author provided the spark for this movement with the 1962 publication of her book, "Silent Spring" which showed the devastating effects of modern pesticides on the natural world.

NASA Astronomy Picture of the Day:

Is this one galaxy or two? Although it looks like one, the answer is two. One path to this happening is when a small galaxy collides with a larger galaxy and ends up in the center. But in the featured image, something more rare is going on. Here, the central light-colored elliptical galaxy is much closer than the blue and red-colored spiral galaxy that surrounds it. This can happen when near and far galaxies are exactly aligned, causing the gravity of the near galaxy to pull the light from the far galaxy around it in an effect called gravitational lensing. The featured galaxy double was taken by the Webb Space Telescope and shows a complete Einstein ring, with great detail visible for both galaxies. Galaxy lenses like this can reveal new information about the mass distribution of the foreground lens and the light distribution of the background source.
