Saturn will be at its biggest and brightest on Sept. 21 — here's how to see it

This weekend, skywatchers are in for a treat as Titan's shadow will cross Saturn, coinciding with the planet's best visibility of 2025. This celestial event, occurring just before Saturn reaches opposition, offers a unique opportunity for enthusiasts and astronomers alike to witness the beauty of our solar system. It's a reminder of the wonders of space and the intricate dance of celestial bodies, making it a must-see for anyone interested in astronomy.

Astronomers have discovered a tiny quasi-moon orbiting Earth, expected to stay with us for nearly 60 years. This fascinating find, smaller than a bowling lane, highlights the dynamic nature of our solar system and offers a unique opportunity for scientific study. Understanding such objects can enhance our knowledge of celestial mechanics and the history of our planet's interactions with space.

In April 2029, the asteroid Apophis, known as the 'God of Chaos', will make a close flyby of Earth, and three space probes are set to observe this significant event. This encounter is crucial for scientists as it provides an opportunity to study the asteroid's composition and behavior up close, enhancing our understanding of near-Earth objects and their potential impact on our planet.

On September 21, a deep partial solar eclipse will be visible from various locations on Earth, offering a unique opportunity for skywatchers to witness this celestial event. It's a reminder of the wonders of our universe and encourages people to engage with astronomy, making it a significant occasion for both enthusiasts and casual observers.

A recent discussion highlights the potential impact of a coronal mass ejection, a rare solar event that could disrupt power and communication systems on Earth. Understanding the risks associated with such events is crucial for preparedness and mitigation strategies, as they can have significant effects on daily life and infrastructure.

On September 18, a potentially hazardous asteroid, comparable in size to the Washington Monument, will make a close flyby of Earth. This event is significant as it allows scientists and the public to observe and study the asteroid's trajectory and characteristics in real-time, enhancing our understanding of such celestial bodies and their potential impact on Earth.

NASA has announced plans to decommission the International Space Station (ISS) by 2030, with no direct replacement in sight. This decision raises questions about the future of human presence in low Earth orbit and the potential for new space exploration initiatives. As the ISS has been a cornerstone of international collaboration in space, its retirement could mark a significant shift in how we approach space research and development.

This week in science news, we explore the discovery of the world's oldest mummy and an intriguing ant species that mates with clones of a distant relative. These findings not only shed light on ancient civilizations but also challenge our understanding of reproduction in the animal kingdom. Such discoveries are essential as they expand our knowledge of biodiversity and evolutionary processes, making them significant for both researchers and enthusiasts alike.

A significant milestone has been reached as sixty states have ratified a global treaty aimed at protecting the oceans, which will officially come into force in January. This treaty is crucial for marine conservation and reflects a growing international commitment to safeguarding our oceans, highlighting the importance of collaborative efforts in addressing environmental challenges.

The CDC's Advisory Committee on Immunization Practices has recently updated its recommendations regarding eligibility for this year's COVID-19 vaccines. This is important as it helps clarify who can receive the updated vaccines, ensuring that those most at risk are protected. Staying informed about these changes is crucial for public health and safety.

The recent decision by Kennedy's vaccine panel to limit access to COVID shots has raised concerns among public health advocates. This move could hinder efforts to achieve widespread vaccination, which is crucial for controlling the pandemic. As COVID-19 continues to pose a threat, limiting access to vaccines may lead to increased infections and complications, making this decision significant for public health.

A recent survey reveals that a quarter of UK university physics departments are at risk of closure due to funding pressures, with four out of five departments already making staff cuts. This alarming trend raises concerns about the future of physics education in the UK and its implications for the country's leadership in scientific research and innovation. The Institute of Physics highlights the urgency of addressing these challenges to ensure the sustainability of physics as a vital field of study.

Exciting news for space enthusiasts! NASA's VIPER moon rover, which was thought to be shelved, is set to be launched by Blue Origin in 2027. This mission aims to hunt for ice on the moon, which could be crucial for future lunar exploration and even for potential human colonization. The collaboration between NASA and Jeff Bezos' company highlights a significant step forward in our quest to understand the moon's resources and pave the way for deeper space missions.
