It may have all started with a moon.

So it is not very likely that random minor impacts caused one planet to almost 70 degrees more than the other while not affecting their spin rates.

Similar spin rates point to much “smoother” processes that took place over eons but dramatically affected the properties of the two gas giants.

AI image generator Dall-E2 is about to find a new host. Microsoft will integrate the AI-based image generator with Microsoft Designer, a video-making tool to be available within the Microsoft Office suite. Till recently, Dall-E2 which is looked down upon as an app meant for only playing around with text prompts will be a part of Microsoft’s AI graphic design app. Designers and video makers who find it difficult to search for unique images can now leverage Microsoft’s Designer app to compose videos with imagery of their choice. Microsoft’s venture is seen as a step toward competing with design major Canva, which boasts more than 100 million active users. During the Ignite Conference held recently, Microsoft announced that it would integrate Dall-E 2 into the yet-to-be-released Designer app as well as existing Bing and Edge.

On Sunday, October 9th, astronomers around the world were privy to an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth, according to a NASA statement published on Thursday. The source of the event was a gamma-ray burst (GRB), one of the most luminous events ever known.

The Moon rotates around the Earth at about the same speed, as it does around its axis, that’s why we can only see one side of it. It means that 41% of its surface hasn’t been explored yet! This fact surprises many people, as we are used to thinking that we know everything about all things in the world. While even our own planet remains a mystery to us.

Red supergiant stars are explosions waiting to happen. They are in the last stage of their life, red and swollen as they fuse heavier elements in…

A deep-space mission is celebrating the first anniversary of its launch from Earth by zipping closer to the planet than the International Space Station’s orbit.

NASA’s Lucy mission launched on Oct. 16, 2021, bound on a 12-year journey to explore the Trojan asteroids, which no spacecraft has ever visited. These asteroids are found at the same distance from the sun as Jupiter, with one phalanx orbiting ahead of the planet and one behind it. All told, Lucy will whiz past nine different asteroids.

If we take the Moon’s current rate of recession and project it back in time, we end up with a collision between the Earth and the Moon around 1.5 billion years ago. However, the Moon was formed around 4.5 billion years ago, meaning that the current recession rate is a poor guide for the past.

Along with our fellow researchers from Utrecht University and the University of Geneva, we have been using a combination of techniques to try and gain information on our solar system’s distant past.

We recently discovered the perfect place to uncover the long-term history of our receding Moon. And it’s not from studying the Moon itself, but from reading signals in ancient layers of rock on Earth.

Dwarf galaxies are small, faint galaxies that are often found in or close to bigger galaxies or galaxy clusters. As a result, they could be impacted by their larger companions’ gravitational effects.

“We introduce an innovative way of testing the standard model based on how much dwarf galaxies are disturbed by gravitational tides’ from nearby larger galaxies,” said Elena Asencio, a Ph.D. student at the University of Bonn and the lead author of the story.

Tides occur when gravity from one body pulls on various areas of another body differently. These are comparable to tides on Earth, which form when the moon exerts a stronger pull on the side of the Earth that faces the moon.

If (or when) human exploration of our planetary neighbours goes ahead, this is a question that future colonists would have to tackle.

What do you need to make your garden grow? As well as plenty of sunshine alternating with gentle showers of rain — and busy bees and butterflies to pollinate the plants — you need good, rich soil to provide essential minerals. But imagine you had no rich soil, or showers of rain, or bees and butterflies. And the sunshine was either too harsh and direct or absent — causing freezing temperatures.
