Tianwen-2 heads toward Kamo'oalewa; a mysterious near-Earth asteroid
Tianwen-2 is heading toward Kamo'oalewa, a small near-Earth asteroid that orbits the Sun in a path similar to Earth's. What makes this asteroid particularly intriguing is the hypothesis that it might be a fragment of the Moon, dislodged by a massive impact event in the distant past.
Upon arrival in 2026, the spacecraft will conduct detailed investigations, including:
Surface imaging and mapping
Material composition analysis
Landing and sample collection
The samples will then be returned to Earth by 2027, providing researchers with rare, untouched material from a near-Earth object—potentially from the Moon's ancient past.
Tianwen-2 to explore mysterious comet after asteroid sample return
Tianwen-2's mission doesn't end after the asteroid sample returns. It will be re-tasked to study the comet 311P/PANSTARRS, known for its active tail and mysterious dust ejection events. This phase of the mission could begin shortly after the asteroid visit and will involve:
Close flybys of the comet's nucleus
Observations of gas and dust activity
Analysis of chemical composition
Scientists hope this exploration could provide vital clues about the origin of Earth's water and organic molecules, helping to answer one of science's oldest questions—how life-supporting ingredients arrived on our planet.
Tianwen-2 sets a new standard with 10-year asteroid-to-comet space voyage
According to
The Astronomy Magazine
, the
Tianwen-2 mission
is planned to last more than 10 years, making it one of the longest and most scientifically rich deep-space missions in China's history. Its dual-phase nature—first targeting an asteroid, then a comet—requires exceptional engineering and mission planning.
This strategy mirrors the complexity and ambition of missions like NASA's OSIRIS-REx and ESA's Rosetta, but with a uniquely Chinese twist: combining asteroid sample return and comet observation into a single, seamless voyage.

Ancient Earth kept boiling for five million years. We now know what happened
Researchers believe they've found the missing piece of the puzzle — and it's rooted in the soil. (Photo: Nasa) CO₂ levels remained sky-high, and so did global temperatures The lessons from 250 million years ago feel eerily relevant Once again, the planet may be approaching a tipping point A new study has shed light on one of Earth's most mysterious climate disasters â€' revealing that the planet remained trapped in extreme heat for millions of years after a mass extinction, largely because the plants didn't grow back fast enough. The event in question is the Permian–Triassic Mass Extinction, also known as the 'Great Dying,' which occurred around 252 million years ago and wiped out nearly 90% of life on Earth. Scientists have long linked this catastrophe to massive volcanic eruptions in Siberia that released huge amounts of greenhouse gases, causing runaway global warming. But here's the puzzling part: the extreme heat didn't subside when the eruptions ended. It lingered for five million years. Now, researchers believe they've found the missing piece of the puzzle â€' and it's rooted in the soil. Using fossil records and climate modeling, scientists reconstructed how plant life changed across the globe during and after the extinction. What they discovered was striking: a massive collapse of land vegetation, especially in tropical areas, led to very low carbon absorption by plants. Without enough greenery to pull carbon dioxide out of the air and store it in the ground, CO levels remained sky-high, and so did global temperatures. The study, published in Nature, shows how important plants are in balancing the Earth's climate. The collapse of ecosystems didn't just affect life on land â€' it created a dangerous feedback loop: fewer plants meant more CO in the air, which meant more heat, which made it even harder for plants to recover. 'This ancient climate crisis carries a clear warning,' say scientists. 'When ecosystems collapse, the climate doesn't just bounce back.' As the modern world faces rapid deforestation and rising carbon emissions, the lessons from 250 million years ago feel eerily relevant. Once again, the planet may be approaching a tipping point â€' and what happened in the past could happen again if natural systems that trap carbon are allowed to fail.

Buck Moon 2025: When and where to watch July's Full Moon of the summer with top viewing tips
Source: BBC As July unfolds across the Northern Hemisphere, the summer sky prepares to dazzle with one of its most anticipated celestial events. As the Buck Moon. Traditionally named for the time when male deer begin growing new antlers, the Buck Moon is July's full Moon and will reach its peak brightness on the night of July 10, 2025. This luminous display isn't the only highlight of the month. From striking planetary alignments to upcoming meteor showers, the season promises a rich schedule of cosmic activity. For skywatchers and stargazers alike, July offers a perfect opportunity to reconnect with the wonders of the universe. What is July's full Moon or Buck Moon The term 'Buck Moon' originates from the indigenous peoples of North America, specifically tribes such as the Algonquin, who named full moons to track seasons and natural cycles. July's full Moon coincides with the time when male deer, or bucks, begin to grow new antlers after shedding them earlier in the spring. According to the Old Farmer's Almanac, these antlers can grow as much as a quarter-inch per day, a biological process driven by testosterone and the lengthening daylight of summer. This Moon, therefore, symbolized regeneration, strength, and preparation for mating season later in the year (Old Farmer's Almanac). Buck Moon 2025: When and how to view July's full Moon According to USA Today reports, July's Full Moon will be visible: Date: Thursday, July 10, 2025 Time of peak illumination: 4:37 PM EDT / 3:37 PM CDT Visibility: Although the Moon reaches peak fullness during daylight hours in North America, the best viewing will occur after local sunset, when it rises fully illuminated on the eastern horizon. Buck Moon 2025: Best viewing tips Time: Begin observing about 30–60 minutes after sunset for best visibility. Location: Choose a spot with a clear view of the southeast horizon. Elevated locations or those with minimal urban light pollution (e.g. rural areas, observatories, or state parks) will yield the clearest sights. Equipment: The Buck Moon is fully visible to the naked eye, but using binoculars or a basic telescope will enhance visibility of lunar surface details like craters, maria (lunar seas), and highlands. Atmospheric effects: When rising, the Moon appears larger and more golden due to Rayleigh scattering—an optical illusion caused by Earth's atmosphere. This is commonly referred to as the "Moon Illusion," a well-documented but still psychologically mysterious phenomenon. Buck Moon 2025 and beyond: What planets you can see and when The full Moon won't be the only celestial body lighting up the night sky on July 10. Several planets will be visible before and after the Moon reaches its peak: Mars: Visible just after sunset in the western sky, though it will set before midnight, so plan for early evening viewing. Venus: Rises around 2:00 am local time in the eastern sky and will shine brightly until sunrise. Saturn: Also visible in the eastern sky near the Moon, but due to the Moon's strong glow, binoculars or a telescope may be required to see its iconic rings. Scientific significance of the full Moon phase A full Moon occurs when the Sun, Earth, and Moon are aligned in a straight line, with Earth between the Sun and Moon. This phase reveals 100% of the lunar surface visible from Earth and plays a role in tidal strength, increasing both high and low tides due to gravitational alignment. The July 2025 Buck Moon will appear in the constellation Capricornus, providing amateur astronomers with context to observe other stars and planetary bodies in proximity. Why July's full Moon is called the Buck Moon The July full Moon carries several names, all of which are rooted in Indigenous traditions and early colonial farming culture. These names were used to track seasonal changes and agricultural patterns. Buck Moon: Named for the time of year when male deer (bucks) begin regrowing their antlers, which reach peak growth in July. Thunder Moon: Refers to the frequent thunderstorms that occur across North America during midsummer. Salmon Moon: Reflects the seasonal migration of salmon upstream to spawn. Feather Molting Moon: Marks the period when ducks and other birds molt feathers, preparing for migration. These traditional names were passed down through generations and are still recognized in modern skywatching guides like The Farmer's Almanac.

One year on this newly discovered plant is just seven days on Earth
Astronomers have discovered a new planet, which is so close to its star that one year lasts just seven days. The planet completes one revolution around the Sun in just seven team found that the planet, dubbed HIP 67522 b, orbits its parent star so tightly that it appears to cause frequent flares from the star's surface, heating and inflating the planet's new planet was discovered by a team of scientists from the Netherlands, Germany, Sweden, and Switzerland, led by Ekaterina Ilin of the Netherlands Institute for Radio Astronomy. They used space-borne telescopes, Nasa's Transiting Exoplanet Survey Satellite) and the European Space Agency's CHaracterising ExoPlanets Telescope (CHEOPS), to track flares on the star. This is the first-ever evidence for a 'planet with a death wish'. Though it was theorised to be possible since the nineties, the flares seen in this research are around 100 times more energetic than expected. Astronomers using the European Space Agency's Cheops mission have caught a clingy exoplanet that seems to be triggering flares of radiation from the star it orbits. (Photo: ESA) advertisementThe planet is orbiting a star named HIP 67522, which was known to be just slightly larger and cooler than our own host star, the Sun. But while the Sun is a middle-aged 4.5-billion-year-old, HIP 67522 is a fresh-faced 17-million-year-old. It bears two planets."The star and the planet form a powerful but likely destructive bond. In a manner not yet fully understood, the planet hooks into the star's magnetic field, triggering flares on the star's surface; the flares whiplash energy back to the planet. Combined with other high-energy radiation from the star, the flare-induced heating appears to have increased the already steep inflation of the planet's atmosphere," Nasa said in a being bombarded with so much high-energy radiation does not bode well for HIP 67522 b. The planet is similar in size to Jupiter but has the density of candy floss, making it one of the wispiest exoplanets ever found. Graphic: ESA Over time, the radiation is eroding away the planet's feathery atmosphere, meaning it is losing mass much faster than expected. In the next 100 million years, it could go from an almost Jupiter-sized planet to a much smaller Neptune-sized planet seems to be triggering particularly energetic flares. The waves it sends along the star's magnetic field lines kick off flares at specific moments. But the energy of the flares is much higher than the energy of the waves. We think that the waves are setting off explosions that are waiting to happen,' points out Ekaterina.- Ends
