One Earth

NASA's Voyager 1, now 25.79 billion kilometres (16.02 billion miles) from Earth, is on course to cross a symbolic milestone: a distance of one light-day, the time light takes to travel between the probe and Earth. The milestone is expected in roughly 40 days, while Voyager 2 trails at 21.58 billion kilometres. Space enthusiasts are marking the probe's continuing journey into interstellar space nearly five decades after launch.

Astronomers at the University of Sydney, led by Dr Manisha Caleb and Dr Themiya Nanayakkara, have announced the detection of an ancient Fast Radio Burst that travelled roughly 10 billion years before reaching Earth, making it one of the oldest cosmic radio signals ever observed. The finding is drawing wide attention among science enthusiasts, with many sharing excitement about what such bursts reveal about the early universe.

Rob Lowe and Jenna Fischer headlined the 2015 sci-fi comedy-drama 'You, Me and the Apocalypse', which followed a group of misfits confronting the end of the world as a comet hurtled toward Earth. The series, a UK-US co-production, lasted just one season but is now being highlighted as a hidden gem worth revisiting.

NASA's Voyager 1, now 25.79 billion kilometres (16.03 billion miles) from Earth, is on track to reach a distance of one light-day — the distance light travels in 24 hours — in about 39 days and 18 hours. Its twin Voyager 2 sits further back at 21.58 billion kilometres. Space watchers are marking the milestone as the farthest human-made object edges deeper into interstellar space.

Jeff Bezos pledged $10 billion to fight climate change in 2020 through his Earth Fund. Six years on, reporting highlights that the money has contributed to protecting Pacific ecosystems, among other climate efforts. The pledge was one of the largest personal commitments to climate action, and attention is returning to what the fund has actually delivered since its launch.

Arafura Rare Earths has begun construction on its Nolans project in the Northern Territory, a landmark development for Australia's critical minerals sector. The mine is set to produce neodymium and praseodymium, key materials for electric vehicle motors and wind turbines, positioning Australia as a significant supplier outside China's dominant rare earths supply chain.

NASA's Voyager 1 probe is set to reach a historic milestone: its distance from Earth will equal one light-day, meaning radio signals take a full 24 hours to travel between the spacecraft and mission control. Launched in 1977, Voyager 1 remains humanity's most distant spacecraft, continuing to transmit data from interstellar space as it marks yet another record.

Researchers at Columbia Climate School's Lamont-Doherty Earth Observatory have received major honors from the American Geophysical Union, one of the most prominent recognitions in the earth and space sciences. The awards, announced by Columbia University and the observatory, acknowledge the scientists' contributions to research on climate, oceans, and the Earth system.

Astronomers using the Gemini North telescope in Hawaii have released high-resolution images of Pa 30, a nebula 7,500 light-years from Earth created by a rare Type Iax supernova that was recorded in 1181. The remnant has long puzzled researchers, and the new imagery is helping clarify the structure and origin of one of the galaxy's most unusual stellar explosions.

Astronomers have released striking new images of Pa 30, the nebula left by the supernova observed from Earth in 1181, showing striking filament structures likened to 'pearl necklaces' radiating from the explosion's centre. The remnant, one of the few supernovae recorded in medieval chronicles, is studied with space telescopes including NASA's, shedding light on how the star's debris expanded over nearly 850 years.

Travel coverage is highlighting Easter Island as one of the most extraordinary destinations in the world. The remote Chilean territory in the Pacific, famous for its monumental moai statues, is being described as unlike anywhere else on the planet. The piece reflects ongoing interest in far-flung, once-in-a-lifetime travel destinations.

Nature photographers are sharing images of fynbos, the distinctive shrubland vegetation unique to South Africa's Cape region. The photos show rocky mountains and native plants of the southern Cape, and the post has drawn attention from a multilingual nature photography community using English, German and Spanish tags. Fynbos is celebrated as one of the world's most biodiverse plant regions, found almost nowhere else on Earth.
