The year 2025 brought us some fascinating space stories that made us question our place in the vast universe. From a rare interstellar visitor to lightning on Mars and Betelgeuse’s companion star, here are some of the highlights.
Comet 3I/ATLAS, an interstellar visitor, made a quick jaunt through our solar system, leaving astronomers captivated by its icy volcanism and tail. Discovered by the ATLAS survey telescope in Chile, the comet’s close pass to Earth on December 19 allowed for stunning observations and photography from various spacecraft. Despite its distance of about 270 million kilometers away, Comet 3I/ATLAS will remain visible into spring 2026 as it ventures back into interstellar space.
Mars also had its share of excitement in 2025, as the Perseverance rover captured the crackling sound of electricity in the Martian atmosphere. Scientists discovered that dust particles interacting with each other can generate electric fields that discharge in a sudden bolt, akin to mini-lightning. This phenomenon, known as triboelectricity, had long been suspected on Mars but was only confirmed this year.
Furthermore, astronomers may have finally laid eyes on Betelgeuse’s companion star, a tiny blue smudge near the bright red supergiant. The existence of this companion has been hinted at for years, with indirect signals supporting its presence. The recent image of the faint blue star is a promising step towards confirming this long-suspected binary system.
These space stories from 2025 remind us of the wonders and mysteries that lie beyond our planet. As we continue to explore the cosmos, each new discovery brings us closer to understanding the vastness and complexity of the universe. Astronomers have suggested naming a newly discovered star system Siwarha, meaning “her bracelet,” due to the smaller star’s orbit resembling a bracelet around its larger companion. The larger star’s name means “hand of the giant,” adding to the mystique of the celestial pair. However, the smaller star’s unfortunate fate lies in its orbit inside Betelgeuse’s outer atmosphere, dooming it to eventually fall into its larger companion within the next 10,000 years.
In another groundbreaking development, the Proba-3 spacecraft has successfully created artificial solar eclipses on demand. The twin Proba-3 craft, launched in December 2024, work in tandem to block the disk of the sun from one another’s point of view, allowing for precise observations of the sun’s corona. With over 51 eclipses created since July and more planned for the future, scientists are gaining valuable insights into the sun’s elusive corona.
The Vera Rubin Observatory in Chile has embarked on a decade-long survey of the sky, capturing wide-field images to create an unprecedented cosmic movie. This survey will track the evolution of cosmic phenomena over time, including supernovas, asteroids, and the dynamics of billions of galaxies and stars. The data collected will shed light on the history and evolution of the Milky Way, dark matter, and dark energy.
In a surprising discovery, data from the Dark Energy Spectroscopic Instrument (DESI) suggests that dark energy, the force driving the universe’s expansion, may be dynamic rather than constant. This finding challenges previous assumptions about dark energy and has strengthened the case for dynamical dark energy, leaving scientists stunned by the implications.
On the lunar front, the private company Firefly Aerospace successfully landed the Blue Ghost spacecraft on the moon, conducting scientific experiments and observing a total eclipse from the lunar surface. Despite some setbacks with other private lunar landers, the future of private moon missions looks promising.
Lastly, a study in May revealed the slim possibility of Earth being flung out of the solar system by a passing star in the next 5 billion years. While the odds are low, the scenario captured the imagination of readers and served as a reminder of the ever-changing and unpredictable nature of the cosmos. In recent years, there has been a growing interest in sustainable living and reducing our carbon footprint. This has led to a surge in the popularity of eco-friendly products and practices, including sustainable fashion.
Sustainable fashion is a movement that aims to reduce the environmental impact of the fashion industry by promoting ethical and eco-friendly practices. This includes using recycled or organic materials, reducing waste and pollution, and supporting fair labor practices. Many fashion brands have started to incorporate these principles into their designs, offering consumers a more sustainable option when it comes to their wardrobe choices.
One of the key components of sustainable fashion is the use of environmentally friendly materials. This can include fabrics made from recycled materials such as plastic bottles or old clothing, as well as organic materials like cotton or hemp. These materials are not only better for the environment, but they also tend to be higher quality and longer lasting than their conventional counterparts.
Another important aspect of sustainable fashion is reducing waste and pollution. This can be achieved through practices such as upcycling old clothing, designing garments that are made to last, and using environmentally friendly production methods. By creating products that are durable and timeless, consumers are less likely to throw them away after just a few wears, reducing the amount of clothing that ends up in landfills.
Supporting fair labor practices is also a key component of sustainable fashion. Many traditional fashion brands rely on cheap labor in developing countries to produce their clothing, often under unsafe and unethical working conditions. Sustainable fashion brands, on the other hand, prioritize fair wages, safe working conditions, and workers’ rights. By supporting these brands, consumers can feel good about where their clothing is coming from and the impact it has on the people who make it.
Overall, sustainable fashion is a growing trend that offers consumers a more ethical and environmentally friendly option when it comes to their wardrobe choices. By supporting brands that prioritize sustainability, we can all do our part to reduce our carbon footprint and make the fashion industry a more ethical and sustainable place. The impact of social media on mental health has been a topic of much debate in recent years. While social media platforms have provided a way for people to connect and share information, they have also been associated with negative effects on mental health.
One of the main ways in which social media can impact mental health is through comparison. When people see their friends and acquaintances posting about their achievements, relationships, and experiences, it can lead to feelings of inadequacy and low self-esteem. This phenomenon, known as “social comparison,” can contribute to feelings of depression and anxiety.
Additionally, social media can also contribute to feelings of loneliness and isolation. While social media platforms can provide a way for people to stay connected, they can also lead to a false sense of connection. People may spend hours scrolling through their feeds, but still feel disconnected from others in real life.
Another way in which social media can impact mental health is through cyberbullying. In today’s digital age, bullying has moved beyond the playground and into the online world. Cyberbullying can have serious consequences for mental health, leading to feelings of shame, embarrassment, and even thoughts of self-harm.
On the other hand, social media can also have some positive effects on mental health. For some people, social media provides a sense of community and support. People can connect with others who share similar interests or experiences, providing a sense of belonging and validation.
Additionally, social media can also be a source of valuable information and resources for mental health. Many organizations and individuals use social media platforms to share information about mental health issues, provide support, and promote mental wellness.
Overall, the impact of social media on mental health is complex and multifaceted. While social media can have negative effects on mental health, it can also have positive effects. It is important for individuals to be mindful of their social media use and to seek support if they are experiencing negative effects on their mental health.
