This rare planetary alignment will be visible from August 10 but will be best viewed later in the month. Here’s everything you need to know to see it at its best.

NASA’s James Webb Space Telescope finds TRAPPIST-1 d lacks an Earth-like atmosphere, narrowing the search for habitable planets.

Chemosynthetic life communities in the Northwest Pacific could offer glimpse of what life might look like on other planets

Fresh off the excitement of the Perseids meteor shower is a chance to see six planets lined up in the sky at once. These events, colloquially known as planet parades, occur occasionally with the most recent one in February showing off all seven planets in ...

How do tidal forces shape a planet's orbital evolution, especially for those in the habitable zone? A recently submitted study aims to answer this question, as an international team of researchers investigated how tidal forces far stronger than those on Earth could influence the orbits of habitable zone planets with highly eccentric paths around low-mass stars.

But it’s not just looks. Rocky composition, general size, orbital behaviors—a lot of those qualities can be the same on both planets and moons. And on the flip side, they can be very different between planets. For instance, our little rocky Earth is a lot more like the Moon than it is, say, Saturn or Uranus.

Prior to flybys, scientists used mathematical laws and observation to determine the characteristics of the planets.

Four planets — Mercury, Venus, Jupiter and Mars — will be visible to the naked eye. To catch sight of Uranus and Neptune, you’ll need a telescope or a pair of binoculars.

In recent years, JWST has revealed a fascinating class of never-before-seen objects, just hanging out in crowded, nebular regions of space. They're called free-floating planetary-mass objects, or FFPMOs, and they're exactly what they sound like: objects with a mass up to 10 Jupiters hanging around all loosey-goosey.
