An astronomer takes us on a tour of the universe to learn about the birth of stars and planets and how they get their spin.
NASA is going back to the Moon.
When the Orion Crew Capsule orbits the Moon there will be no one on board. But the mission will mark a key step in bringing humans back to Earth’s dusty sidekick.
There is a U.S. flag on the Moon, but in the future, countries may start to turn access to the Moon and asteroids into serious wealth.

Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
The Sun rises in Midland, Michigan, shortly after 8a.m. on Jan. 13, 2017.
The winter solstice is past, but bundle up – January is when winter really arrives in many parts of the Northern Hemisphere.
The International Space Station is a great example of how space has, for the most part, been a peaceful and collaborative international arena.

Activities in space today are far more numerous and complicated compared to 1967, before humans had landed on the moon or Elon Musk had been born. Two experts explain the need for better laws to keep space peaceful.
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.
The planet and the way we live on it are constantly changing.

The Earth is constantly changing in natural ways, but most of those changes are very slow. Humans are speeding up other changes with global warming.
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.
A red blood moon is caused by sunlight passing through the Earth’s atmosphere.

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.
Leap years were devised in Julius Caesar’s time, to fix the pesky problem that Earth’s year isn’t exactly 365 days. But 15 centuries later, our calendars were still slightly askew.
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 bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
The Northern Hemisphere gets its biggest dose of daylight.
