A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth’s surface. But whether the alignment … Read more
The chance it’s an artefact is just 1%.
And then there were two—maybe. Astronomers say they have found a second plausible candidate for a moon beyond our solar system, an exomoon, orbiting a world nearly 6,000 light-years from Earth. Called Kepler-1708 b-i, the moon appears to be a gas-dominated object, slightly smaller than Neptune, orbiting a Jupiter-sized planet around a sunlike star—an unusual … Read more
The solar system lies inside a structure called the Local Bubble some 1000 light years across – and a map of its surface shows it is the site of star formation Space 12 January 2022 Artist’s illustration of the Local Bubble with star formation occurring on the bubble’s surface Leah Hustak (STScI) The star-forming regions … Read more
The Solar System floats in the middle of a peculiarly empty region of space. This region of low-density, high-temperature plasma, about 1,000 light-years across, is surrounded by a shell of cooler, denser neutral gas and dust. It’s called the Local Bubble, and precisely how and why it came to exist, with the Solar System floating … Read more
Before Earth and the other planets in our Solar System existed, the Sun may have been surrounded by giant rings of dust similar to Saturn’s, according to a new study. Those rings of dust may have prevented Earth from growing into a “super-Earth” – a type of planet that is about twice the size of Earth and … Read more

Right now our solar system is barreling into a region of space that we know next to nothing about. For about 60,000 years, our sun has been traversing the local interstellar cloud (LIC), a region of gas and dust within a mostly empty bubble that was carved out of the Milky Way by supernovae millions … Read more
Comet Leonard is falling out of view, but not without putting on one last show. Discovered just a year ago, the comet, formally known as Comet C/2021 A1, made its closest approach to Earth on Dec. 12, marking the climax of a month full of prime observing opportunities. As the comet has continued on its … Read more
A new video of solar streamers evokes the streaking stars seen during spacecraft hyperdrives in “Star Wars.” The new NASA video from the Parker Solar Probe shows these mysterious sun structures up close for the first time, flowing past the spacecraft like interstellar fireflies. Previously, we could only catch a glimpse of streamers during solar … Read more
