SPECULOOS-2c - Another Super-Earth Candidate

In 2022, Belgian researchers discovered LP 890-9c, also known as SPECULOOS-2c. This exoplanet is about 40% larger than Earth and orbits its star much closer than Earth does the Sun. However, because its star is smaller and cooler, SPECULOOS-2c might possess conditions that are conducive to life.

Cosmic Wonders and Phenomena

The cosmos never ceases to amaze with its vast array of wonders, from Saturn's intriguing moon Titan to the enigmatic ultra massive black holes. These discoveries continue to fuel our curiosity and deepen our understanding of the universe.

Liquid-Filled Canyons on Titan

In 2013, NASA's Cassini mission made a remarkable discovery on Titan, Saturn's largest moon. The mission revealed deep canyons filled with liquid, suggesting that Titan might have conditions that could support life. This finding opened new avenues for studying the potential for life on other moons and planets in our solar system.

Ultra massive Black Holes

Observations from NASA's Chandra X-ray Observatory have identified black holes that are ten times larger than previously thought. These ultra massive black holes are growing more rapidly than the surrounding stars, challenging existing theories about black hole formation and growth.

Cosmic Microwave Background Radiation

The cosmic microwave background (CMB) radiation offers a glimpse into the early universe, just 380,000 years after the Big Bang. Initially detected in 1965, the CMB has been studied extensively, with the Planck satellite providing a detailed map in 2013. These observations have significantly enhanced our understanding of the universe's infancy and its subsequent evolution.

Space Discoveries That Changed Our Understanding

Collision of Neutron Stars

In 2017, the collision of two neutron stars was observed, a momentous event that provided new insights into stellar evolution. This collision produced gravitational waves, ripples in spacetime predicted by Einstein's theory of general relativity and led to the creation of heavy elements like gold and platinum. This discovery underscored the dynamic and interconnected nature of cosmic events.

Tsunamis on Mars

Research funded by NASA in 2016 revealed that Mars experienced two mega-tsunamis, likely triggered by asteroid impacts. These findings support the hypothesis that Mars once had a vast ocean beneath its arid surface, offering clues about the planet's climatic history and potential for past life.

Alcohol-Spewing Comet Lovejoy

In 2015, a team led by Nicolas Biver from the Paris Observatory discovered that Comet Lovejoy was emitting ethyl alcohol, a key component of alcoholic beverages. Along with 21 other organic molecules, including a type of sugar, this finding suggests that comets may have delivered the building blocks of life to Earth, providing a vital piece of the puzzle in our quest to understand the origins of life.

Unveiling Planetary Origins

The formation and evolution of planets have long fascinated scientists, and recent discoveries have provided new insights into these processes, offering a clearer picture of how our planet and others came to be.

Planet-Building Clumps and Pebble Accretion

In 2018, planetary scientists uncovered evidence supporting the "pebble accretion" model, where tiny clumps of dust and ice in space coalesce to form larger planetary bodies. This discovery, made by researchers at NASA's Astro materials Research and Exploration Science Division and Ames Research Center, has significantly advanced our understanding of early planet formation.

The Synestia Theory of Earth's Formation

A 2017 study proposed that Earth may have once been a "synestia," a hot, donut-shaped mass formed after a massive collision. This theory offers a novel perspective on the formation of Earth and the Moon, suggesting that such colossal impacts were instrumental in shaping our planet's early history.

Groundbreaking Findings on Familiar Worlds

Ice Volcanoes on Ceres

NASA's Dawn mission made a groundbreaking discovery in 2015 on Ceres, the largest object in the asteroid belt between Mars and Jupiter. The mission identified a mountain, Ahuna Mons, near the equator, which is believed to be an ice volcano. Unlike terrestrial volcanoes that erupt molten rock, Ahuna Mons may have erupted a mixture of cold, salty water and mud. This finding sheds light on the geological processes that have shaped Ceres and suggests that cryovolcanism may be more common in the solar system than previously thought.

Water on the Moon's Surface

In 2018, NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) confirmed the presence of water on the sunlit surface of the Moon. This discovery was made in the Clavius Crater and revolutionized our understanding of the Moon. The detection of water opens new possibilities for future lunar exploration and the potential use of lunar resources, such as in-situ water for drinking, fuel, and other purposes.
