A Massive Rock Orbiting The Sun Appears to Have Originated Surprisingly Close to Us

According to a new analysis, a chunk of rock that hangs out near Earth's orbital path along the Sun seems to be made of the same material as the Moon , suggesting that it broke off at some point to be flung into space. But how, and when, remains a mystery.

The rock is named 469219 Kamoʻoalewa, and astronomers already found it interesting before this latest development.

Astronomers discover a sub-Neptune exoplanet orbiting nearby star

Recently, a group of astronomers led by Nicole Schanche of the University of Bern in Switzerland has confirmed another TOI monitored by TESS. While observing a nearby M-dwarf known as TOI-2257 (other designation TIC 198485881), a transit signal was identified in the light curve of this star.

"This work presents the discovery and characterization of TOI-2257b, a sub-Neptune in a relatively long-period orbit around an M3V star.

China's Tianwen 1 Mars orbiter changes orbit to begin planetary survey | Space

China's Tianwen 1 Mars orbiter has changed its orbit to begin a remote sensing survey of Mars after months of supporting the Zhurong rover.

The spacecraft has been orbiting Mars since February, and in May Tianwen 1 released the Zhurong rover for its successful landing attempt in Mars' Utopia Planitia.

Bad Astronomy | HD 3167 has 2 planets orbiting at right angles to a third | SYFY WIRE

One of the most obvious things about our solar system is that all the big planets orbit the Sun in very nearly the same plane. If you looked at the solar system "from the side" it would look very nearly flat.

This is a consequence of how our planets formed . Billions of years ago, a cloud of gas and dust started to collapse.

TESS Detects Planet in Orbit Around Two Stars | SETI Institute

27 days, 2 transits, 3 eclipses, 1st circumbinary planet detected from a single sector of TESS data

November 10, 2021, Mountain View, CA – Researchers announced that they detected a planet in a 200-days orbit around two stars – known as a circumbinary planet – from observations of just one TESS sector over an observation period of 27 days.

Strong aurorae dazzle astronauts from space | Astronomy.com

In late October, NASA’s Solar Dynamics Observatory captured an intense flare erupting from the Sun . A few days later, the crew of the International Space Station (ISS) saw what astronaut Thomas Pesquet called “the strongest auroras of the entire mission.

The striking show occurred because flares such as the one recently emitted from the Sun release waves of charged particles that scatter throughout the solar system.

A Black Hole Was Found Outside Our Galaxy For The First Time With an Ingenious Method

If they're not actively devouring material, which most stellar-mass black holes are not, they emit no radiation that we can detect. Therefore, we have to resort to other means of detecting them – such as looking for stars that seem to be in a binary orbit with... nothing.

Now, for the first time, astronomers have managed to pin down a black hole outside the Milky Way galaxy using this method.

After many centuries, research suggests new facets to the blinking 'Demon Star'

Lauri Jetsu, an astrophysicist at the University of Helsinki, is following a tradition that may stretch back thousands of years.

For more than a decade, he's studied the bright star Algol, one of the most unusual stars in the sky, with its brightness visibly changing every few days.

China launches new set of Yaogan Earth reconnaissance satellites | Space

China launched the first set of three satellites for a new series of classified Yaogan reconnaissance satellites on Saturday (Nov. 5), continuing the country's rapid rate of orbital missions.

A Long March 2D lifted off at 10:00 p.m. EST (0300 GMT, 11:00 a.m. local Time), rising into blue skies over the wooded hills surrounding the Xichang Satellite Launch Center in southwest China.
