First Observation of Gravitational Waves

September 14th, 2015 9 years ago

The LIGO and Virgo collaborations made the groundbreaking discovery of gravitational waves, a phenomenon predicted by Albert Einstein. Detected on September 14, 2015, these ripples in spacetime resulted from the merger of two black holes approximately 1.3 billion light-years away. The observation marked a monumental milestone in astrophysics, as it confirmed Einstein's theories while opening new pathways in the study of the universe's most violent events.

Fourpeaked Mountain Erupts After Millennia

September 17th, 2006 18 years ago

The Fourpeaked Mountain in Alaska erupted, marking its first eruption in over 10,000 years. The volcano, located in the Aleutian Range, displayed an explosive eruption characterized by ash plumes that reached several miles into the atmosphere. Monitoring agencies reported that the eruption prompted flight cancellations and warnings for local residents as the ash spread across the area. This unexpected volcanic activity underscored the dynamic nature of volcanic systems and raised awareness regarding the geological processes occurring in Alaska’s volcanic landscape.

Discovery of the 'Oh-My-God' Particle

October 15th, 1991 33 years ago

An ultra-high-energy cosmic ray, named the 'Oh-My-God' particle, was detected at the University of Utah's HiRes observatory. It carried energy equivalent to 40 million times that of the most powerful proton accelerators of the time. This unprecedented level of energy raised questions about the cosmic processes generating such high-energy particles and provided insights into particle physics and astrophysical phenomena.

Astronomers Discover Rings of Uranus

March 10th, 1977 48 years ago

In March 1977, astronomers using the Kuiper Airborne Observatory made a significant discovery by detecting the rings of the planet Uranus. This finding occurred during observations of the planet's transit across a distant star. As Uranus passed in front of the star, the rings briefly blocked the starlight, allowing researchers to identify them. This was the first announcement of the existence of rings around Uranus, greatly enhancing our understanding of the planet's characteristics and its place in the solar system.

Hubble Declares Andromeda a Separate Galaxy

November 23rd, 1924 100 years ago

Edwin Hubble published a groundbreaking report revealing that the Andromeda Nebula, previously thought to be part of our Milky Way, is actually a distinct galaxy located millions of light-years away. His findings, based on observations made at the Mount Wilson Observatory in California, fundamentally altered the understanding of the universe's structure. Hubble's work, featured in The New York Times, opened up new avenues for astronomical study and shifted perceptions about our place in the cosmos.
