Popular belief suggests the highest tides in the St. Lawrence River are reached around the equinoxes. In truth, they arrive close to the solstices.
Space weather can affect satellites in a number of different ways, from frying electronics to increasing drag in the atmosphere.
The sun has entered a phase causing more chances to see the northern lights in the UK, an expert explains.
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.
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.
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.
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°C. But higher above the surface, in the atmosphere, it suddenly shoots up to more than a million degrees!
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.
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.

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.
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.
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.
