The James Webb Space Telescope is the biggest orbital telescope ever built and is scheduled to be launched into space on Dec. 18, 2021.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
Four people – none of them trained astronauts – launched into orbit aboard a SpaceX Dragon capsule on Sept. 15, 2021.
The Inspiration4 mission sent four civilians to space for three days. Though still funded by a billionaire, the mission is a step forward in the nascent space tourism industry.
Gravity feels like it’s pulling everything toward Earth, but why?

Gravity is something every person on Earth intuitively understands: It is what keeps you on the ground. But how come gravity pulls down, rather than pushes up? Einstein came up with the answer.
Virgin Galactic’s Unity VSS spacecraft went on a suborbital test flight in May 2021.
Both Virgin Galactic and Blue Origin are sending spacecrafts – and their billionaire founders – into suborbital flight. But what differentiates a suborbital flight from a trip around Earth?
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.

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.
It’s unlikely falling space junk will destroy property or kill a person.

Chances are small that space junk will destroy property or harm a person, and existing space law could deal with such an event. But current law doesn’t address the bigger problem of space pollution.

The Tiangong space station is set to become a second long-term habitat for humans in orbit around Earth.
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
Satellites monitor climate change, guide people with GPS and keep us connected through texts and social media, but they’re under threat.
New geological research reveals information about the Earth’s orbit and climate from billions of years ago.
Layers of rock provide a historical record of variations in the Earth’s orbit, revealing information about the planet’s climate billions of years ago.
A comet-gazing opportunity to close out the year.

A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
China’s Tiangong-1 space station is due to hit Earth, and Australia is in the crash landing zone.

China’s Tiangong-1 space station is hurtling around Earth out of control and about to come crashing down. It’s just one of thousands of pieces of space junk left orbiting our planet.
What goes in doesn’t go out?
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
The SpaceX Falcon Heavy rocket takes off from Cape Kennedy in Florida, USA on 06 February 2018.
The launch of Elon Musk’s Falcon Heavy rocket is undoubtedly a spectacular feat of engineering - but the release of a sports car into orbit also says something about our values as human beings.
time of moonrise and moonset and the shape of the Moon change throughout the month.

When and where you see the Moon in the daytime depends on what phase it is in.
As long as clouds don’t get in the way, the view should be spectacular.
A bunch of uncommon things all happening at the same time mean this full moon will have some special attributes.
Sunrise over Brisbane.
A solar day is a measure of how long it takes the Earth to rotate from one noon to the next, and today’s summer solstice also happens to be the longest solar day of the year.
Without satellites, modern technologies such mobiles phones and GPS would not exist.

We’ve all seen videos of satellites being blasted off into space - but once they’re locked in orbit around the earth, how do we bring them back down?
Tiny CubeSats are ready to be our eyes in the skies.
