New Webb Image Captures Clearest View of Neptune’s Rings in Decades
NASA’s James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet’s rings in more than 30 years, but its cameras reveal the ice giant in a whole new light.

Watch a Live Feed from NASA’s DART Spacecraft on Approach to Asteroid Dimorphos (upcoming)
NASA’s Double Asteroid Redirection Test (DART) has one single instrument onboard – the Didymos Reconnaissance and Asteroid Camera for Optical Navigation, aka the DRACO camera. DRACO serves as the spacecraft’s eye and will guide DART to its final destination: impact with asteroid Dimorphos. The stream you'll be watching will be a real-time feed from the DART spacecraft enabled through the DRACO camera sending one image per second to Earth.
In the hours before impact, the screen will appear mostly black, with a single point of light. That point is the binary asteroid system Didymos which is made up of a larger asteroid named Didymos and a smaller asteroid that orbits around it called Dimorphos.
As the
At 23:14 UTC, the DART spacecraft is slated to intentionally crash into asteroid Dimorphos. This stream will be delayed due to the time it takes the images to arrive at Earth, plus additional time for feeding the images to various platforms.
After impact, the feed will turn black – due to a loss of signal. After about 2 minutes, this stream will turn into a replay – showing the final moments leading up to impact. That replay file will also become available on NASA websites and social media accounts.
DART is a spacecraft designed to impact an asteroid as a test of technology. DART’s target asteroid is NOT a threat to Earth. This asteroid system is a perfect testing ground to see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future.

Asteroid-smashing planetary defense test was a success, NASA confirms
Last month’s DART mission ‘nudged’ an asteroid moonlet enough to noticeably change its orbit
When a spacecraft slammed into an asteroid last month, it pushed it closer to its companion and sped up its orbit by about 32 minutes. It’s a huge milestone for the field of planetary defense; it establishes that it may be possible for humans to significantly change the path of a potentially hazardous asteroid especially if we have warning that one is on the way.

Solar eclipse up close
NASA's Artemis 1 Orion spacecraft aces close moon flyby in crucial engine burn
Orion zoomed just 80 miles (130 kilometers) above the lunar surface Monday (Nov. 21) at 7:44 a.m. ET. and completed an engine burn needed to continue its historic mission. NASA's Artemis 1 mission fired its engines close to the moon today (Nov. 21), finishing the maneuver successfully out of communication with Earth.
Artemis 1's uncrewed Orion spacecraft has been cruising toward the moon since Wednesday morning (Nov. 16), when it launched atop NASA's gigantic Space Launch System (SLS) rocket.
The burn "sent Orion close enough to the lunar surface to leverage the moon's gravitational force, and swing the spacecraft once around the moon toward entry into a distant retrograde orbit," NASA's Sandra Jones said during an Artemis 1 livestream Monday (Nov. 21) at 8:28 a.m. EST, nearly an hour after the burn took place.

We Just Got The Most Detailed View of an Exoplanet Atmosphere Yet – And It's Active
WASP-39b, a gas giant about 700 light-years away, is turning out to be quite the exoplanetary treasure.
Earlier this year, WASP-39b was the subject of the first-ever detection of carbon dioxide in the atmosphere of a planet outside the Solar System.
Now, an in-depth analysis of data from the James Webb Space Telescope (JWST) has given us an absolute goldmine of information: the most detailed look at an exoplanet atmosphere yet...

The Sun accounts for about 99.86% of the total mass of the Solar System. The Sun's mass is approximately 1,988,550,000,000,000,000,000 billion kg. Which is equivalent to about 330,000 Earths.
According to our calculations, on January 21, 2023, the New Moon will be at its closest distance to Earth for the last 992 years.
The next time the New Moon is this close to Earth will be 345 years from now, making this the closest New Moon in 1337 years.

2023 January 21 356,568 km

Massive eruption explodes from the sun
A massive eruption of magnetized particles burst from the sun on Tuesday (Jan.3), accompanied by a powerful six-hour-long solar flare.
The eruption, a so-called coronal mass ejection (CME), emerged from a sunspot on the far side of the sun, and will not hit Earth, experts say. CMEs are clouds of highly charged particles from the sun's upper atmosphere, the corona. If directed at Earth, they reach the planet within a few days. Interactions of the charged solar particles with Earth's magnetic field trigger beautiful aurora displays but also cause all sorts of problems such as power blackouts, GPS disruptions and satellite malfunctions. Solar flares, on the other hand, are bright flashes of light that arrive at the planet within eight minutes and can briefly disrupt radio communications.

Another Earth-size exoplanet discovered in habitable zone of nearby star
The planet, named TOI 700 e, is one of four known planets orbiting a cool star approximately 100 light-years away. The planet was discovered by NASA’s planet-hunting telescope, the Transiting Exoplanet Survey Satellite.
NASA’s planet-hunting telescope, the Transiting Exoplanet Survey Satellite (TESS), has discovered a second Earth-size planet within the habitable zone of a nearby star.
Named TOI 700 e, the planet is one of four known planets orbiting a cool star approximately 100 light-years away. The system was already known to host one planet, called TOI 700 d, in the habitable zone, but recent research that will be published in the Astrophysical Journal Letters reveals it is joined by another planet inside its orbit. The other two planets in the system, TOI 700 b and TOI 700 c, orbit closer to the star and, as such, are likely to have higher temperatures, putting them outside of the habitable zone.

The sun has produced a massive coronal hole and is "spewing a stream of solar wind directly toward Earth," according to Spaceweather.com. See a one-week time-lapse of the hole in the Sun's atmosphere from NASA's Solar Dynamics Observatory.
Asteroid Apophis is coming back
It has 1/37 chance for impact
Apophis is a near-Earth asteroid that was once considered to be a potential threat to Earth, but has been ruled out for at least the next century. Here are some key points about Apophis:
Orbit and close approaches: Apophis orbits the Sun every 323 days and makes periodic close approaches to Earth.
That’s closer than most geosynchronous satellites and 10 times closer than the moon.
Impact risk: When Apophis was first discovered, astronomers calculated a small chance of it impacting Earth in 2029, 2036, or 2068.
Scientific interest: Apophis is an object of intense scientific interest because of its close encounters with Earth and its potential to provide insights into the origin and evolution of asteroids.
