NASA New Sun Discovery ( Strange Universe)
On the left side of the frame is the full circle of the Sun. It appears in a golden yellow color, but splotchy and with thin yellow wisps extending from the surface. Some areas are very bright and others almost black. The whole Sun rotates steadily, with one full rotation taking 12 minutes in this time lapse. There are usually only a few bright regions visible at a time and they shift and flash like small fires. From these regions there are wispy loops reaching up above the surface that rapidly change shape and size.
On the right side of the frame are two white-outlined squares with enlargements of interesting regions of the Sun.

NASA | Fiery Looping Rain on the Sun
Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona.
On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun's lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays -- a phenomenon known as coronal rain.
Over the course of the next day, hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, themselves, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface.
The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

NASA | Evolution of the Moon
From year to year, the moon never seems to change. Craters and other formations appear to be permanent now, but the moon didn't always look like this. Thanks to NASA's Lunar Reconnaissance Orbiter, we now have a better look at some of the moon's history

Everything You Need to Know About Pipe Repair Tape
Everything You Need to Know About Pipe Repair Tape
Repairing a pipe can vary depending on the type of pipe and the nature of the damage. Here are some general steps you can follow for repairing a common household pipe:
Identify the problem: Determine the location and extent of the damage to the pipe. Common issues include leaks, cracks, or burst pipes.
Turn off the water supply: Locate the main water shut-off valve and turn it off to prevent further water flow. This will minimize the damage and allow you to work on the pipe safely.
Drain the pipe: Open all faucets connected to the affected pipe to drain any remaining water. You can also use towels or buckets to catch any excess water that may come out.
Patch small leaks: For small leaks or cracks in pipes, you can use pipe repair tape or epoxy putty to create a temporary seal. Follow the instructions on the product packaging to apply the tape or putty properly.
Replace damaged section: If the damage is more severe or the pipe is completely burst, you may need to replace a section of the pipe. Cut out the damaged section using a pipe cutter or hacksaw, ensuring clean and straight cuts. Take the removed section to a hardware store to find a suitable replacement.
Install new pipe section: Measure and cut the replacement pipe section to fit precisely. Clean the ends of the existing pipe and the replacement section. Apply plumber's tape or pipe joint compound to the threaded ends, and use pipe connectors, couplings, or compression fittings to join the pipes securely.
Test for leaks: Once the repair is complete, turn the water supply back on and check for any leaks. Allow the water to run for a few minutes and inspect all the connections carefully.
Insulate and secure pipes: To prevent future damage, consider insulating exposed pipes to protect them from freezing temperatures. Additionally, ensure that the pipes are properly supported and secured to prevent unnecessary stress and movement.
It's important to note that if you are unsure about the repair process or the damage is extensive, it's best to contact a professional plumber to handle the repair for you. They have the necessary expertise and tools to ensure a proper and long-lasting fix.
