Discovered in 2013, the Pink Planet orbits a sun-like star located 57 light-years from Earth. At roughly 25 times the mass of Jupiter, it sits near the fuzzy boundary between giant planets and brown dwarfs. So, astronomers refer to it as a "planetary-mass companion," meaning that it's a planet-sized object orbiting a star. Breakthroughs, discoveries, and DIY tips sent six days a week.

The rise of AI tools that instantly answer questions and complex problems could make humans less intelligent, the Royal Observatory Greenwich has warned. The Observatory, one of the UK's oldest purpose-built scientific institutions, is known for its contributions to astronomy. Paddy Rodgers, director of the Royal Museums Greenwich group which oversees it, said its rich history of research showed the power of human knowledge and curiosity - and the need to avoid complete dependence on AI. A reliance solely on instant answers risks losing the habits of questioning and evaluation that underpin knowledge, expertise and innovation, he said. Rodgers' remarks come amid an ongoing transformation of the Royal Observatory in a project called First Light. The project hopes to seize on the passion of all the astronomers over the last 350 years, and interpret that passion through science, Rodgers told the BBC.

Science Space Deep Space Fastest comet ever recorded spewed 70 Olympic pools' worth of water daily More information Adding us as a Preferred Source in Google by using this link indicates that you would like to see more of our content in Google News results. A new study of the interstellar comet 3I/ATLAS led by the University of Michigan shows that its water has a remarkably high content of deuterium. This form of hydrogen is comparatively less abundant in our solar system, enabling researchers to glean new insights about other planetary processes at work in our galaxy. Breakthroughs, discoveries, and DIY tips sent six days a week. Astronomers knew 3I/ATLAS wasn't a local comet not long after first spotting it in July 2025 .

'Project Hail Mary' may be fiction, but this list could still come in handy. An artist's impression of a theoretical planet orbiting a redder star, which could cause microbes and plants on the planet's surface to reflect very different colors from Earth's green forests. Breakthroughs, discoveries, and DIY tips sent six days a week. Life on Earth is a precious thing, especially given what astronomers know about the visible universe. Although researchers have so far identified over 6,000 exoplanets beyond our solar system, only a handful of them be suitable for human visitors.

Science Space Deep Space Black Holes For the first time, astronomers witnessed the birth of a'magnetar' These fast spinning, magnetic neutron stars may power some of the brightest supernovae in the cosmos. Artist's conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets of charged particles emanate from the magnetar along its rotation axis. Breakthroughs, discoveries, and DIY tips sent six days a week. In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory.

No one was injured at the home in Germany, but the ESA is investigating. The bright object traveled over at least five countries. Breakthroughs, discoveries, and DIY tips sent six days a week. The European Space Agency (ESA) is investigating a bright fireball that lit up the early evening sky across at least five countries on March 8th. At around 5:55 p.m. local time, residents across Belgium, France, Germany, Luxembourg, and the Netherlands spotted a glowing object soaring across the sky for an estimated six seconds before disintegrating into multiple fragments.

An artist's impression of 3I/ATLAS is shown as it passes near the Sun, illuminating one side of the comet. On the side of the comet closer to the sun, the methanol gas is shown in blue, with icy dust grains still present in the gas. On the dark side of the comet, the hydrogen cyanide is shown in orange. Breakthroughs, discoveries, and DIY tips sent six days a week. The comet 3I/ATLAS is well on its way back into deep space, but the famous cosmic visitor continues to fascinate astronomers.

The interstellar space rock shows off the illuminating effects of its brush with the sun. Breakthroughs, discoveries, and DIY tips sent six days a week. After months of unprecedented observations, astronomers are bidding goodbye to the beloved comet 3I/ATLAS . First spotted in July 2025, the frigid, dusty space rock is only the third known interstellar object to pass through the solar system, offering researchers the rare opportunity to examine a visitor from deep space. Among other discoveries, scientists have since confirmed that the interstellar comet is the fastest ever recorded as well as covered in ice volcanoes --and definitely not extraterrestrial tourists .
