Was NASA's DART mission a success? | BBC Sky at Night Magazine

An epic trial run of a plan that may one day save Earth took place in September 2022. But what happened? And what next?

NASA's Double Asteroid Redirection Test (DART) launched on 24 November 2021, heading towards the Didymos system – a large asteroid orbited by a smaller 'moon', Dimorphos.

Shocking! This asteroid CRASHED into Earth, says NASA; Check asteroid impact site

In the midst of all the terrifyingly close asteroid flybys, NASA has now revealed that an asteroid actually crashed into the Earth just days ago!

NASA has revealed that the asteroid lit up the sky as it flew over Southern Ontario, Canada on Saturday, November 19. What's shocking is that this 3-foot asteroid was detected just 3.5 hours before impact! However, such small-sized asteroids do not pose a risk to the planet.

How satellites, radar and drones are tracking meteorites and aiding Earth's asteroid defense

These were two excellent indications that there should be a patch of ground covered in meteorites somewhere north of Port Augusta. But how could we track them down?

My colleagues and I who work on the Desert Fireball Network (DFN) , which tracks incoming asteroids and the resulting meteorites , had a couple of ideas: weather radar and drones.

Pic of the Day: Smallest radar instrument to be flown in space

This 10-cm box will make history as the smallest radar instrument to be flown in space, highlights the European Space Agency, and it will be the first radar to probe the interior of an asteroid.

Its target destination? The Dimorphos asteroid, which on the night of 26 September had its orbit diverted and a vast 10 000 km plume sent out into space following a collision with NASA's DART mission craft.

Man Keeps Rock For Years, Hoping It's Gold. It Turns Out to Be Far More Valuable : ScienceAlert

Armed with a metal detector, he discovered something out of the ordinary – a very heavy, reddish rock resting in some yellow clay.

He took it home and tried everything to open it, sure that there was a gold nugget inside the rock – after all, Maryborough is in the Goldfields region, where the Australian gold rush peaked in the 19th century.

Are Solar Panels a Good Investment? - The New York Times

Q: We were considering installing solar panels on the roof of our home in Nassau County, New York, even though we expect to move within five years. Several real estate agents advised us not to install the panels as they would adversely affect the resale value down the road.

A: Solar panels can be a valuable investment for a homeowner, with benefits that extend beyond resale value. But not all homes reap those benefits, and you'll need to do some research to figure out if the considerable upfront costs are worth it.

Mars: A world that might have been, now stripped by a solar wind - Coast Reporter

Mars is this month’s big deal. Its motion through the stars stopped on Oct. 30 and became retrograde motion as Earth began to overtake it prior to opposition. As a result, Mars moved westward from above Betelgeuse in Orion to closer to Aldebaran in Taurus.

Mars begins December at magnitude -1.8 and its disc at its maximum of 17.2” (arc-seconds). Its closest approach occurs at 18:00 on Nov. 30, although its exact opposition (to the sun) occurs on Dec. 7 at 22:00. (All times are Pacific Standard.

What Planets Are Retrograde December? 2022 Is Ending With A Bang

If things have felt a little too quiet in the cosmos, things are about to get very interesting.

During the month of December, only one planet will *actually* be stationing retrograde — it just so happens to be the most ominous, Mercury. Typically, Mercury retrogrades only three times per year, but 2022 obviously had to be extra and go out with a bang.

A newly discovered planet has the diameter of Jupiter but eight times its mass, giving it twice the density of Earth despite being composed mostly of gas.

The exoplanet , which lies around 310 light-years outside the solar system in the constellation Centaurus, orbits a sun-like star and is just 15 million years old, making it a relative infant in cosmic terms and when compared to our 4.6 billion-year-old planet.

Nascent gas giant planets may be lurking in dusty disk

Using data from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and the Jansky Very Large Array (VLA) in New Mexico, they found that the disk is 80–100 times wider than the distance from the sun to the Earth, a span known as an astronomical unit .

The disk is unstable and collapsing in a region roughly 20 astronomical units from its young star. The VLA had previously identified several clumps of matter in the same area, and their formation may be driven by this gravitational instability.

Measuring The Obliquities Of The TRAPPIST-1 Planets With MAROON-X - Astrobiology

However, M dwarfs, which are the most promising targets for atmospheric follow-up, are underrepresented in terms of obliquity characterization surveys due to the challenges associated with making precise measurements.

Mars Once had Enough Water for a Planet-Wide Ocean 300 Meters Deep - Universe Today

Today, Mars is colloquially known as the “Red Planet” on a count of how its dry, dusty landscape is rich in iron oxide (aka. “rust”). In addition, the atmosphere is extremely thin and cold, and no water can exist on the surface in any form other than ice.

In other words, the composition of these meteorites represents Mars’ original crust before asteroids deposited water and various elements on the surface. Since Mars does not have active plate tectonics like Earth, the surface is not subject to constant convection and recycling.
