Astronomers are getting concerned about the growing number of Starlink and other satellites
SpaceX launched 49 more satellites last week to join a growing list of more than 1,800 satellites. The Elon Musk-owned company has been approved to build a total of 12,000 Starlink satellites to provide broadband connectivity. But more and more satellites are coming from not just SpaceX but other companies, and astronomers are increasingly concerned.
To help address astronomical observations in dense space with satellites, the International Astronomical Union (IAU) launched the IAU Centre for Protecting Dark and Quiet Skies from Satellite Constellation. The center aims to help solve these problems, not only by astronomers, but also by satellite operators from different countries.
“The International Astronomical Union believes in the principles of dark and radio quiet skies, which are essential not only to advance our understanding of the universe, of which we are a part, but also to the cultural heritage of all mankind and the protection of nocturnal wildlife, “The International Astronomical Union said in a statement.
Satellite constellations affect astronomical observations because they reflect sunlight and leave bright spots. Anything astronomers observe in the night sky can be disturbed by these light streaks. The concern was particularly raised by the Zwicky Transient Facility (ZTF) at the Palomar Observatory in California, which said twilight observations were affected by the bright appearance of Starlink satellites. That could make searching for objects like comets and asteroids difficult.
The International Astronomical Union hopes the center will help address questions about the growing number of satellite constellations. It will provide information and resources on “the negative effects of satellite constellations on terrestrial optical and radio astronomy observations and human enjoyment of the night sky.”
The centre has already received positive feedback from other astronomical organisations including the Royal Astronomical Society (RAS). Members of the center are primarily located in Tucson, Arizona, USA, and Jodrell Bank, near Manchester, UK, but it will cater to institutions and individuals worldwide.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine
Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.
When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.
While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress.

Why recovery is key for muscle growth
According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.
Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.
Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.
Role of overtraining syndrome and deload weeks
Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.
Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.
Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
