The BepiColombo spacecraft just flew past Mercury - its ultimate destination - for the first time. The resulting photos reveal a moon-like surface.
Etienne Léopold Trouvelot sketched the cosmos for Harvard. His pastels capture solar flares, eclipses, star clusters, and Jupiter's biggest storm.
Mars and Venus will be a mere half-degree apart, or about the width of an index finger at arm's length, in the sky on Monday and Tuesday nights.
SpaceX's Starship cargo craft could hoover up dead satellites, used rocket parts, and other debris simply by opening its door, CEO Elon Musk said.
Venus used to be a lot like Earth, but something turned it into an inhospitable pressure cooker. NASA and the ESA want to find out what happened.
Two telescopes worked together to capture jaw-dropping images of Jupiter through different types of light.
If you unfurled Saturn's rings into lines, all the planets in the solar system could line up comfortably along their length.
Musk said SpaceX would land its reusable Starship rockets on Mars years before European space companies begin to focus on launch systems.
The United Arab Emirates Space Agency released its first image of Mars on Sunday. The photo was taken by its Hope Probe, which reached the red planet on Tuesday. NASA’s Perseverance rover is scheduled to land next Thursday. Visit the Business section of Insider for more stories. The United Arab […]
Mercury, Jupiter, and Saturn are aligned in the night sky, appearing closer together than they have been since 2000. When three planets move into such a conjunction, it’s known as a planetary trio. Here’s how to see the conjunction on Monday night. Visit Business Insider’s homepage for more stories. Mercury, […]
Jupiter and Saturn will align in the night sky on Monday. It will be the closest they have appeared in 800 years. The two planets move into alignment, or conjunction, every 20 years. But this year they will be so close that they will look like a “double planet.” The […]
Our solar system orbits an invisible point at its centre called the barycenter, from which its mass is evenly distributed. Even the sun orbits this point – so the centre of the solar system doesn’t always align with the centre of our star. Planetary scientist James O’Donoghue made an animation […]
Astronomers photographed two planets orbiting a sun-like star for the first time ever. Because the planets are so far from their star – much further than any planet in our solar system – they come through clearly in the image. Future telescopes could study this young star and its planets […]
A mesmerising time-lapse video from NASA chronicles the sun’s activity over the last decade. Each second in the video represents a year of the sun’s life, making it look like a rotating disco ball. Bright flashes are eruptions, while dark patches are sunspots. Visit Business Insider’s homepage for more stories. […]
Visualising distant planets, moons, and comets in our solar system can be challenging. Typically, astronomers use images from NASA missions or artistic renditions to show what space objects look like. Now, planetariums like the American Museum of Natural History’s Hayden Planetarium are turning to a new method – data visualisation […]
Proxima Centauri, the closest star to the sun, might have a second planet in its orbit, according to a new study. Astronomers think the planet, called Proxima c, is a super-Earth that formed far from the icy region where scientists think such worlds are born. But Proxima c might not […]
Astronomers have discovered a new Earth-sized planet outside our solar system, 100 light-years away. The planet, named TOI 700 d, is in its star’s habitable zone and has the potential to hold liquid water. Future research could give scientists more information about the planet’s surface and atmosphere. Visit Business Insider’s […]
