Astronomers have confirmed that Betelgeuse has a hidden companion star, Siwarha, which creates a dense gas wake as it moves through the star's atmosphere, explaining long-standing variability and behavior changes in this red supergiant, with future observations planned for 2027.
The article discusses the discovery of a remarkable anti-tail jet in the interstellar object 3I/ATLAS, observed by the Hubble Space Telescope, which challenges conventional understanding of cometary behavior and suggests the need for further scientific investigation into its unusual features and alignment with the Sun.
NASA's Hubble Space Telescope observations suggest Betelgeuse has a hidden companion star named Siwarha, which influences its brightness variations and may help explain its dimming behavior, providing insights into the star's evolution and potential supernova event.
NASA's Hubble has discovered 'Cloud-9', a starless, gas-rich dark matter cloud that is a relic of early galaxy formation, providing new insights into dark matter and the universe's origins.
Images from the Hubble Space Telescope reveal a complex, evolving jet structure in the interstellar object 3I/ATLAS, including a prominent anti-tail jet aligned with the Sun and three other jets with a symmetric angular arrangement, raising questions about their natural or technological origins.
Astronomers have captured the first visible-light image of 'Dracula’s Chivito,' the largest and most chaotic planet-forming disk ever observed, located about 1,000 light-years away. This massive, asymmetric disk exhibits unusual features like extended filaments on one side, challenging previous assumptions about the serenity of planet nurseries. It serves as a scaled-up model of early solar system conditions, offering new insights into the complex processes of planet formation.
Astronomers observed a rare collision between two asteroids around the star Fomalhaut, providing insights into planet formation processes and highlighting the dynamic and collision-rich environment of this nearby star system. The event also helped distinguish between actual planets and dust clouds, refining methods for exoplanet detection.
The Hubble Space Telescope captured a stunning image of the spiral galaxy NGC 3370 in Leo, which is crucial for understanding galaxy formation and measuring cosmic distances using Cepheid variables and Type Ia supernovas, helping to refine our knowledge of the universe's expansion.
NGC 2775 is a distant galaxy whose unusual features challenge astronomers' ability to classify it, as it exhibits characteristics of both elliptical and spiral galaxies, possibly due to past galaxy mergers, and remains a subject of ongoing study.
Scientists observed a mysterious, long-lasting gamma-ray burst that lasted nearly a day, unlike typical bursts that last milliseconds to minutes. The event, detected by NASA and Chinese space telescopes, appears to originate from beyond our galaxy and may involve an unusual black hole or a star being torn apart, making it a unique and puzzling cosmic phenomenon.
NASA's Hubble Space Telescope has observed a white dwarf star consuming a Pluto-like object rich in water ice and volatiles, providing insights into the future of our solar system as the star evolves into a white dwarf and potentially pulls in icy bodies from its Kuiper Belt.
A new analysis of Hubble images of interstellar object 3I/ATLAS reveals an unprecedented tenfold elongation of its sunward glow, attributed to ice fragments rather than dust, and highlights several anomalies that suggest the object may be more intriguing than a typical comet, prompting further investigation.
Astronomers have discovered one of the most massive binary star systems in our galaxy, NGC 3603-A1, with two stars weighing 93 and 70 times the Sun's mass, orbiting each other every 3.8 days. This discovery, aided by archival Hubble data and new observations, provides valuable insights into stellar evolution and the origins of binary black holes, highlighting the dynamic and extreme conditions in star-forming regions like NGC 3603.

3I/ATLAS is an interstellar object observed to lack a typical cometary tail, with surface characteristics suggesting a large, rocky body around 20-46 km in diameter. It shows signs of CO2 ice shedding but no water vapor, raising questions about its origin and composition. Its trajectory and properties hint it may have been purposefully directed into the Solar System, and further observations are needed to understand its true nature.
