Wonders of Space

Jupiter and Venus are headed for a rare planetary conjunction in the predawn sky. They are the two brightest planets in the solar system and will pass extremely close to each other, appearing as a double star in the sky. As explained in this video, this conjunction will be even more spectacular than the Great Conjunction of 2020 involving Jupiter and Saturn.

2022 is going to be an exciting year for astronomy enthusiasts. Besides the annual meteor showers and planetary oppositions, 2022 has some rare astronomical events to offer. They include double occultation, planetary conjunctions, supermoons, and eclipses. This video talks about eight rare things that will be seen in 2022.

A few years ago, it was predicted that a red nova will be visible in the skies of 2022. It was the first-of-its-kind prediction that excited astronomers worldwide. But, is it really true? What's the whole story behind this prediction?

Chandrayaan-3 is the third and most recent lunar Indian Space Research exploration mission under the Chandrayaan programme. It consists of a lander named Vikram and a rover named Pragyan similar to Chandrayaan-2, but does not have an orbiter. Its propulsion module behaves like a communication relay satellite. The Chandrayaan-3 lander stands about 2 meters tall and has a mass of just over 1,700 kg (3,747.86 lb), roughly on par with an SUV. It is designed to deploy a smaller, 26-kg lunar rover.

In the vast expanse of the cosmos, where stars shimmer and galaxies collide, lies a tapestry of mysteries waiting to be unraveled. Get ready to be captivated by the wonders and the biggest mysteries that lie beyond our reach, awaiting discovery in the depths of the universe in this 4K space documentary. Topics covered- 1. Olber’s Paradox (Why is space black?) 2. First Contact 3. Vanishing of Planet Dagon (Fomalhaut b) 4. Pioneer Anomaly

Everything that happens on the International Space Station revolves around one thing: Earth, sixteen times a day! So for Earth Day 2021, NASA offers a gift you can’t get anywhere else with this leisurely view of our home planet, from 250 miles up, rendered in extraordinary ultra-high definition video. Hit play, relax, and enjoy. This 4K footage was recorded between 2019 and 2020.

This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2022, as viewed from the Southern Hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon's orbit position, sub-Earth and subsolar points, and distance from the Earth at true scale. Craters near the terminator are labeled, as are Apollo landing sites, maria, and other albedo features in sunlight.

This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2022, as viewed from the Northern Hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon's orbit position, sub-Earth and subsolar points, and distance from the Earth at true scale.

Video Description: 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. This video chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun’s outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

Take a virtual tour of the Moon in all-new 4K resolution, thanks to data provided by NASA's Lunar Reconnaissance Orbiter spacecraft. As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.
