Hubble Telescope’s 35th Anniversary: A Cosmic Gallery of Mars, Nebulae, and Colliding Galaxies.....
Milestones of a Legendary Observatory.
Since its launch on April 24, 1990, NASA’s Hubble Space Telescope has revolutionized our understanding of the universe. As it celebrates its 35th anniversary, Hubble continues to deliver breathtaking images and groundbreaking science. Its latest releases include stunning portraits of Mars, a butterfly nebula, star-forming regions, and interacting galaxies—each revealing a new cosmic wonder.
These images not only highlight Hubble’s enduring power but also its unique role in astronomy, complementing new observatories like the James Webb Space Telescope (JWST). Let’s explore these celestial masterpieces and their scientific significance.
1. Mars: A Detailed Portrait of the Red Planet
Hubble's anniversary images include a sharp, close-up view of Mars, when the planet was at its closest approach to Earth. The image reveals:
Dust storms swirling across the rust-colored terrain
Bright polar ice caps made of water and frozen carbon dioxide
Major geological features, such as Olympus Mons, the solar system's tallest volcano
Why it matters
Hubble's observations provide context for NASA's rover missions, helping scientists track seasonal changes and global dust activity. The images are also valuable for planning future missions, including the Mars Sample Return Mission, which aims to bring Martian soil back to Earth.
2. The Butterfly Nebula: A Dying Star's Beautiful Farewell
One of Hubble's most captivating anniversary images is the Butterfly Nebula (NGC 6302), a binary planetary nebula located about 3,800 light-years away. This cosmic "moth" was created when a dying star ejected its outer layers, leaving behind:
Sculpted "wings" of gas spanning 2 light-years
Bright streams of ionized oxygen (blue) and nitrogen (red)
A central star, once like our Sun, is now a white dwarf
Scientific Insights
The Butterfly Nebula helps astronomers understand how mid-sized stars like our Sun eventually die. Its complex structure also reveals how magnetic fields and stellar winds shape the nebula into such stunning shapes.
3. The Tarantula Nebula: A Stellar Nursery at Work
Hubble revisited the Tarantula Nebula (30 Doradus), one of the largest and most active star-forming regions in our galactic neighborhood. Located 160,000 light-years away in the Large Magellanic Cloud, this nebula contains:
A superstar cluster with some of the most massive stars known
A vast column of gas and dust, where new stars are being born
The remnants of supernova explosions, which sow the seeds of future star formation
Why astronomers study it
The Tarantula Nebula serves as a cosmic laboratory for studying how stars are born, evolve, and die. Its extreme conditions resemble those of the early universe, providing clues about how the first galaxies formed.
4. Galactic collision: A preview of the Milky Way's future
Hubble also captured Arp 273, a pair of interacting galaxies locked in a gravitational dance. The arms of the larger spiral galaxy are dramatically bent by the pull of the smaller one, creating:
A tidal tail of stars and gas ejected into space
A bright knot of new star formation resulting from the collision
A preview of what could happen when the Milky Way and Andromeda collide 4 billion years from now
The science behind galactic mergers
Such collisions are common in the universe and play an important role in the evolution of galaxies. Hubble's observations help scientists understand how galaxies grow, merge, and reshape over time.
Hubble's legacy and future
Despite being 35 years old, Hubble is an important tool for astronomers. Its sharp vision in ultraviolet and visible light complements JWST's infrared capabilities, allowing scientists to study the universe across multiple wavelengths.
What's next for Hubble?
Continued operations through at least the late 2020s
More deep space discoveries, from exoplanets to distant supernovae
Ongoing collaborations with JWST and future telescopes

Chandragupta Maurya vs the Greek Empire: The Clash That Reshaped Ancient India
Background: Alexander’s Invasion and Its Aftermath The roots of the conflict trace back to Alexander the Great’s invasion of India in 326 BCE. Although Alexander defeated King Porus at the Battle of Hydaspes, his army refused to advance further east. Upon his return westward and his death in 323 BCE, Alexander’s vast empire fractured among his generals, known as the Diadochi.

The Biggest Unsolved Mysteries in History That Still Baffle the World
1. The Disappearance of the Indus Valley Script The Indus Valley Civilization, which flourished around 2500 BCE in present-day India and Pakistan, was one of the world’s earliest urban societies. It boasted advanced city planning, sophisticated drainage systems, and standardized brick construction. However, one of its greatest mysteries is its undeciphered script. Thousands of inscriptions have been found on seals, pottery, and tools, yet no one has been able to decode their meaning. Unlike Egyptian hieroglyphs or Mesopotamian cuneiform, the Indus script lacks a bilingual inscription that could serve as a key. Without understanding their language, historians remain uncertain about their political systems, religious beliefs, and even the reasons behind the civilization’s decline. 2. The Lost City of Atlantis First mentioned by the Greek philosopher Plato around 360 BCE, Atlantis was described as a powerful and technologically advanced civilization that sank into the ocean “in a single day and night of misfortune.” Ever since, Atlantis has captured the imagination of scholars, explorers, and conspiracy theorists. Some believe Atlantis was purely allegorical—a moral lesson created by Plato. Others argue it may have been inspired by real events, such as the volcanic destruction of the Minoan civilization on the island of Thera (Santorini). Despite centuries of searching, no definitive archaeological evidence has proven Atlantis existed, leaving it suspended between myth and history. 3. The Construction of the Great Pyramids of Giza The Great Pyramids of Egypt, built over 4,500 years ago, remain among the most astonishing architectural feats in human history. The largest, the Pyramid of Khufu, consists of over two million stone blocks, some weighing more than 80 tons. The mystery lies not in who built them, but in how they were constructed with such precision using ancient tools. How were massive stones transported across vast distances? How were they lifted and placed so accurately? While theories range from ramps to complex pulley systems, no single explanation fully satisfies all the evidence. The pyramids continue to challenge our understanding of ancient engineering capabilities. 4. The Voynich Manuscript Discovered in 1912 by rare book dealer Wilfrid Voynich, the Voynich Manuscript is a handwritten book filled with strange illustrations, unknown symbols, and an indecipherable script. Radiocarbon dating places its creation in the early 15th century. Despite intense analysis by cryptographers, linguists, and even artificial intelligence, the text remains unreadable. Some believe it is a sophisticated code, others think it represents a lost language, while skeptics argue it could be an elaborate hoax. The manuscript’s purpose—whether medical, astronomical, or magical—remains one of the greatest puzzles in literary history. 5. The Amber Room Often referred to as the “Eighth Wonder of the World,” the Amber Room was a chamber decorated with panels made entirely of amber, gold leaf, and precious stones. Created in Prussia in the early 18th century, it was later gifted to Russia and installed in the Catherine Palace. During World War II, Nazi forces dismantled the room and transported it to Königsberg. After the war, it vanished without a trace. Countless searches have failed to locate it, leading to theories that it was destroyed, hidden in underground bunkers, or lost at sea. Its fate remains one of the most enduring art mysteries of modern history. 6. The Identity of Jack the Ripper In 1888, a series of brutal murders terrorized London’s Whitechapel district. The killer, known as Jack the Ripper, murdered at least five women and vanished without being identified. Despite numerous suspects proposed over the years—ranging from doctors and artists to members of the royal family—no conclusive evidence has ever confirmed the killer’s identity. Advances in forensic science, including DNA analysis, have reopened the case multiple times, yet the truth remains elusive, preserving Jack the Ripper as history’s most infamous unidentified criminal. 7. The Nazca Lines Etched into the desert plains of southern Peru, the Nazca Lines are enormous geoglyphs depicting animals, plants, and geometric shapes. Created between 500 BCE and 500 CE, these figures are best seen from the air. The mystery lies in their purpose. Were they astronomical calendars, religious symbols, irrigation markers, or ceremonial pathways? How did the Nazca people design such large-scale drawings without an aerial perspective? While scholars lean toward ritualistic and astronomical explanations, no definitive answer has been found. 8. The Fate of the Roanoke Colony In 1587, English settlers established a colony on Roanoke Island in present-day North Carolina. When supply ships returned three years later, the entire settlement had vanished. The only clue left behind was the word “CROATOAN” carved into a post. There were no signs of violence or struggle. Theories suggest the settlers may have assimilated with Native American tribes, relocated, or perished due to disease or famine. Despite extensive research, the true fate of the “Lost Colony” remains unknown. Why These Mysteries Endure What makes these mysteries so compelling is not just their unanswered questions, but what they reveal about humanity. They highlight the limits of our knowledge and remind us that history is not a complete record, but a fragmented story shaped by time, loss, and interpretation. Even with satellites, artificial intelligence, and advanced archaeology, some truths remain just out of reach. These unsolved mysteries continue to inspire research, debate, and imagination, proving that the past is far from silent—it is waiting for us to listen more closely.
