A giant coronal hole has appeared on Sun's surface: According to the National Oceanic and Atmospheric Administration (NOAA), coronal holes occur when the magnetic fields that hold the sun in place suddenly open up.
The sun is spewing solar wind right at the Earth after an enormous dark hole opened up in the sun's surface. With scientists calling this temporary gap unprecedented at this stage of the solar cycle.
On December 2, the dark hole - known as a coronal hole - took shape near the sun's equator.
Within 24 hours it reached its maximum width of roughly 497,000 miles (800,000 kilometres), according to Spaceweather.com. Since Dec. 4, the coronal hole has been pointing directly at Earth.
It was initially expected that the hole could spark a moderate (G2) geomagnetic storm, which could trigger radio blackouts and strong auroral displays. However, the solar wind has been less intense than predicted. Although at high latitudes, auroras are still possible.
Solar activity has been ramping up this year as the sun nears its solar maximum - the explosive peak in its roughly 11 year solar cycle. Despite this, the new coronal hole is not supposed to be part of this increase in solar activity as they are usually more common during solar minimum. When they emerge during a solar maximum, they are normally located near the sun's poles, rather than the equator.

With every passing year we are losing our Earth and other planets of the solar system: Pluto's atmosphere may completely collapse and freeze by 2030, according to a 28-year study of the small, cold dwarf planet on the edge of our solar system. Every 248 years, Pluto completes another orbit around the sun.
In 2018, NASA said its Voyager 1 and 2 missions confirmed decades ago that Saturn is losing its rings. "The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn's magnetic field," NASA said.
42 million trees are cut down each day.
That's 15.3 billion every year, Humans have already destroyed around 46% of the trees on Earth.
Only 36% of the world's rainforests remain intact.

Earth's intense gravity may rip space rocks apart, reducing the risk of 'planet killer' asteroids
Every year, dozens of asteroids come closer to our planet than the moon is, and yet catastrophic collisions are exceedingly rare.

Earth and other terrestrial planets probably use their gravitational forces to tear apart asteroids ― but this creates more streams of smaller asteroids.

Want to get into stargazing? A professional astronomer explains where to start
A good place to start if you're a budding astronomer is to learn your way around the night sky. When I was young, this involved getting hold of a planisphere (a star map, you can make your own here), or a good reference book.

Spacetime ripples detected in 2023 continue to puzzle astronomers. Could they be from the dawn of the universe?
Scientists are still hunting for the source of the faint, persistent hum of gravitational waves discovered reverberating through the Milky Way last year. Those waves could point to more than one tantalizing source, new research suggests.

NASA tests 3D-printed, rotating detonation rocket engine
Looking to the future, NASA is investigating several technologies that will allow it to accomplish some bold objectives. This includes returning to the moon, creating the infrastructure that will let us stay there, sending the first crewed mission to Mars, exploring the outer solar system, and more. This is particularly true of propulsion technologies beyond conventional chemical rockets and engines. One promising technology is the rotating detonation engine (RDE), which relies on one or more detonations that continuously travel around an annular channel.

ESA's tiny pinhole thruster is ready for production
Rocket propulsion technology has progressed leaps and bounds since the first weaponized rockets of the Chinese and Mongolian empires. They were nothing more than rocket-powered arrows and spears but they set the foundations for our exploration of space. Liquid propellant, ion engines and solar sails have all hit the headlines as we strive for more efficient methods of travel but a team has taken the next leap with a palm-sized thruster system that could boost future tiny spacecraft across the gulf of space.

For next hundred years it would seem that earth has two suns. Yeah, Betelgeuse won't explode tomorrow but after 100,000 years it will. Even though Betelgeuse is million times bigger than our sun, it has a lifespan of just 10 million years. Wish I'll be alive to see that ✨🌠

Is a black hole stuck inside the sun? No, but here's why scientists are asking
Just before the end of 2023, astrophysicist Matt Caplan announced the release of a new paper that boasts a rather outlandish title: "Is there a black hole in the center of the Sun?" I asked for the short answer, and, as you may expect, he said "probably not." But that's far from the end of the story.
