'Oumuamua still puzzling scientists 5 years after discovery
Although its origins are still hazy, interstellar objects like 'Oumuamua may be the product of wandering planets in young planetary systems.

Astronomers detect heaviest element ever found in exoplanet atmospheres
Astronomers have spotted an unexpected chemical element high within the atmosphere of two sizzling exoplanets where liquid iron and gems rain down from the skies. The two exoplanets, which orbit separate stars beyond our solar system, are ultrahot gas giants called WASP-76b and WASP-121b. Astronomers used the European Southern Observatory’s Very Large Telescope to detect barium at high altitudes in the atmosphere of each exoplanet.

Astronomers detect an inflated 'hot Jupiter' exoplanet
An international team of astronomers has discovered a new inflated "hot Jupiter" exoplanet as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-21b is about 30% larger and more than two times as massive as Jupiter. The finding was detailed in a paper published October 3 on arXiv.org.

Mock lava worlds will help the James Webb Space Telescope understand exoplanets
Scientists have modeled the molten surfaces of 16 different types of lava worlds in the laboratory, creating a catalog of basic types of rocky exoplanet that astronomers using the James Webb Space Telescope can reference to characterize alien worlds.

Ultra Rare Diamond Suggests Earth’s Mantle Has an Ocean’s Worth of Water
A beautiful blue flaw in a gem-quality diamond from Botswana is actually a tiny fragment of Earth’s deep interior—and it suggests our planet’s mantle contains oceans’ worth of water. The flaw, technically called an inclusion, looks like a fish eye: a deep blue center surrounded by a white haze. But it’s really a pocket of the mineral ringwoodite from 660 kilometers down, at the boundary between the upper and lower mantle.

Earth is ‘well-hidden’ from extraterrestrial civilizations hunting for habitable planets
Earth is “well-hidden” to extraterrestrial observers using photometric microlensing to hunt for habitable planets that might support life, an international team of researchers has concluded. The findings could also help to narrow down the best areas of the galaxy to target in our own searches for extraterrestrial intelligence (SETI).

Scientists stumped by strange polygon-shaped cyclones on Jupiter
Enormous polygon-shaped cyclone systems at Jupiter’s north and south poles have left scientists baffled over how they maintain their bizarre but beautifully geometric shapes for years. The hurricane-force storms — each the size of the continental United States — have remained inexplicably stable in their strange configurations since they were first discovered by the Juno spacecraft in 2017.

If you had to name a probe for Uranus, what would you call it?
Uranus always seems to be the butt of the joke, but this icy planet is actually one that scientists hope to dive deeper into in the future. In fact, many are already pushing for more missions to probe Uranus and learn more about the planet. That’s why some folks, like the people behind Twitter account @ExploreIGO, are trying to push for missions by coming up with a Uranus probe name.

SPECULOOS discovers a potentially habitable super-Earth
A first planet, LP 890-9b (or TOI-4306b), the innermost in the system, was initially identified by NASA's Transiting Exoplanet Survey Satellite (TESS), a space mission dedicated to the search for exoplanets orbiting nearby stars. This planet, which is about 30% larger than the Earth, completes an orbit around the star in just 2.7 days. The ULiège researchers used their ground-based SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) telescopes to confirm and characterise this planet, and also to probe the system in depth for other planets that might have been 'missed' by TESS.

Scientists discover two new "super-Earth" planets just 100 light-years away — and one may be suitable for life
An international team of scientists announced on Wednesday that they have discovered two new "super-Earth" planets just 100 light-years away. Both of them are significantly larger than our own planet — and one of them may even be suitable for life.

Discovery of alien world with strange, tilted orbit puzzles astronomers
The orbit of an exoplanet around a star in a binary star system has been portrayed in three dimensions for the first time. The planet orbits its star at a different angle to the plane of the orbit of the two stars, and the misalignment could offer clues as to how planets form in binary systems.

A new exoplanet 100 light years from Earth may be entirely covered in water
An international team of researchers led by the University of Montreal discovered an exoplanet that could be covered entirely in water. The planet TOI-1452b is about 100 light years away from Earth, located in Draco Constellation. It's larger in size and mass compared to Earth and is located in the "habitable zone," which means the temperature is just right for the liquid water to exist.

‘Incredible’ Jupiter images revealed by NASA’s James Webb telescope
Stunning images taken by NASA’s James Webb Space Telescope show Jupiter in new glory. Fifth in line from the sun, Jupiter is the largest planet in our solar system — more than twice as big as all the others combined. If Earth were the size of a grape, Jupiter would be the size of a basketball, NASA says.

What a decade of Curiosity has taught us about life on Mars
Ten years ago, engineers at NASA's Jet Propulsion Lab celebrated the successful landing of its fourth robot on Mars, The Curiosity rover. Now old enough to enter the fifth grade, the Curiosity rover was set on its mission in 2012 to determine whether the red planet could have ever supported life.
