Solar System

A huge comet making its journey towards the solar system has begun to show a tail. A newly released image shows the fuzzy coma, confirming that it is indeed a comet and may be one of the largest ever discovered.

Mercury’s disproportionately massive core may be the result of the Sun’s powerful magnetic influence rather than the consequence of a cataclysmic collision with another body in the ancient past, according to the results of a new study.

The outskirts of our solar system is teeming with mysterious objects – and now one of them is heading our way. Astronomers have discovered a minor planet that’s about to make its closest pass to the Sun on its 600,000-year orbit.

Maxeon Solar Technologies reckons that it's come up with a way to install PV panels on the roofs of buildings that may not be able to support conventional setups, creating frameless, thin and lightweight panels that can be adhered directly to a roof.

The first comet known to visit our Sun after being born around an alien star may be the most pristine comet ever discovered, new research has found.

For a long time, Pluto was the farthest object we knew in the solar system, but it’s a cosmic stone’s-throw away compared to more recent discoveries. Now astronomers have confirmed the most distant world of all – the appropriately-named Farfarout.

Researchers at the Paris Observatory's Institute of Celestial Mechanics and Ephemeris Calculation have found that the unusual tilt of Saturn's axis is due to the periodic gravitational pull of its moons over the last billion years.

Based on isotope analysis of meteorites, scientists at the Lawrence Livermore National Laboratory have determined that our solar system may have formed much faster than previously thought.

Jupiter’s moon Europa is a fascinating world, with a global subsurface ocean encased in an icy shell and plumes of water that vent into space. A new study has simulated how these plumes might originate, revealing a surprisingly dynamic ice ball.

NASA and NOAA have confirmed that the Sun has entered a new solar cycle, with activity beginning to ramp back up from its minimum in December 2019. This next cycle is forecast to be rather quiet, continuing a long-term trend of reduced activity.

Harvard scientists have suggested that the Sun had a long-lost twin. An ancient binary solar system helps explain the strange structure of the Oort cloud, and possibly the hypothetical Planet Nine. Best of all, the team outlines how we could check.

Could there be a tiny black hole hiding in our own backyard? It’s been suggested that the hypothetical Planet Nine is actually a black hole, and now astronomers have proposed how we might find it in the next few years, using an upcoming telescope.
