A ‘super-puff’ planet like no other — ScienceDaily

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found. This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM’s Institute for Research on Exoplanets (iREx) suggests that […]

The planet is dying faster than we thought

Humanity is barreling toward a “ghastly future” of mass extinctions, health crises and constant climate-induced disruptions to society — one that can only be prevented if world leaders start taking environmental threats seriously, scientists warn in a new paper published Jan. 13 in the journal Frontiers in Conservation Science. In the paper, a team of […]

Mars digger bites the dust after 2 years on red planet

This Dec. 6, 2018 image made available by NASA shows the InSight lander. The scene was assembled from 11 photos taken using its robotic arm. On Thursday, Jan. 14, 2021, NASA declared the craft dead after failing to burrow deep into the red planet to take its temperature. (NASA via AP) NASA declared the Mars […]

One Planet Summit kickstarts year of crucial environment talks

The endangered Crowned Lemur. So far, efforts to protect and restore nature on a global scale have failed spectacularly Global leaders will try to reignite international environmental diplomacy on Monday, with a biodiversity summit that launches a critical year for efforts to stem the devastating effects of global warming and species loss. Momentum on climate […]

First Detection of a Built-In Wobble on Another Planet

In a first for a solar system body other than Earth, scientists have detected the Chandler wobble on Mars, a repeated movement of the poles on the surface of the planet away from its average axis of rotation. The Chandler wobble arises when a rotating body isn’t a perfect sphere. This imbalance affects […]

Your retirement account can also help protect the planet

Investing can be intimidating, but it doesn’t have to be hard. (Pexels/) Retirement planning is already fraught with anxiety. It involves financial calculations and long-term thinking, and most Americans probably would rather not think about it. But though it’s unpleasant to think about, our retirement accounts actually play an influential role in the world: they’re […]

Mysterious asteroid the size of a dwarf planet is lurking in our solar system

There’s a giant asteroid somewhere out in the solar system, and it hurled a big rock at Earth. The evidence for this mystery space rock comes from a diamond-studded meteor that exploded over Sudan in 2008. NASA had spotted the 9-ton (8,200 kilograms), 13-foot (4 meters) meteor heading toward the planet well before impact, and […]

If a planet has a lot of methane in its atmosphere, life is the most likely cause

Once it’s deployed and in position at the Earth-Sun Lagrange Point 2, it’ll begin work. One of its jobs is to examine the atmospheres of exoplanets and […]

Humans are destroying our ‘perfect planet,’ Attenborough says

Powerful natural forces on our planet and in our solar system work together to sculpt and support life on our fragile pale blue dot.  A new five-part series called “A Perfect Planet,” narrated by the legendary Sir David Attenborough, explores how these natural forces have worked together to make life possible — and how a […]

This alien world could help us find Planet Nine in our own solar system

This 11-Jupiter-mass exoplanet called HD106906 b occupies an unlikely orbit around a double star 336 light-years away and it may be offering clues to something that might be much closer to home: a hypothesized distant member of our Solar System dubbed “Planet Nine.” This is the first time that astronomers have been able to measure […]
