Penguins will have the best seat in the house as a total solar eclipse passes over Antarctica on December 4. Australia and New Zealand will experience a minor partial eclipse, but not a noticeable one.
It only takes light about eight minutes to go from the Sun to Earth.

The fastest things ever made by humans are spacecraft, and the fastest spacecraft reached 330,000 mph – only 0.05% the speed of light. But there are ways to go faster.
A telescope in the outer solar system would be able to do unique science that is impossible closer to the Sun.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.

For the first time ever, astronomers have astrophysical evidence that Jupiter and many other planets will survive the death of the Sun.
Astronomers have found a way to estimate the number of stars in the universe.

Scientists have a good estimate on the staggering number of stars in the universe.
The temperature of the Sun’s surface is about 6,000℃. But higher above the surface, in the atmosphere, it suddenly shoots up to more than a million degrees!
Scientists have been studying lunar samples brought back from Apollo missions to understand the geologic history of the Moon.
Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.

When heat in doesn’t equal heat out, Earth sees changes.
It can stretch your mind to ponder what’s really out there.

Astronomers know a lot about what’s in outer space – and think it’s possible it never ends.
Test out scientific ideas, connect with your ancestors or just marvel at the beauty of nature.
The vast majority of people will be oblivious to what’s going on above their heads.
Alfvén waves, first proposed 80 years ago, could explain why the sun’s atmosphere is so much hotter than its surface.

This Wednesday night, everywhere in Australia will have a box seat for a spectacular total eclipse of the Moon.

In the early morning of May 26, 2021, there will be a super blood-red lunar eclipse. The show will be spectacular and can all be explained by the orbits of the Earth and Moon.
Fire a set of high-power lasers at a tiny speck of hydrogen isotopes and you can initiate nuclear fusion, the process that powers the Sun.
National Ignition Facility
Scientists are working on ways to make lots of energy by converting matter into energy. The trick is keeping the process under control. One possibility is nuclear fusion – the Sun’s power source.
Proxima Centauri is the closest star to the solar system and is home to a potentially habitable planet.

Astronomers just measured the largest flare ever from Proxima Centauri, humanity’s closest neighboring star. These flares could be bad news for life trying to develop on a planet orbiting the star.
April’s super full moon was known as the pink moon because it heralds the arrival of spring flowers.

Sea level is still rising, and when that lunar cycle starts upward again, it will mean double trouble for places like Miami.

Satellites, space stations and astronauts, aviation, GPS, power grids and more can be affected.
The greenhouse effect and plate tectonics are essential for maintaining water on the Earth’s surface.

The presence of water on the Earth’s surface is the result of a subtle balance between different mechanisms in the atmosphere and below the surface.
Falling into a black hole is easily the worst way to die.
