First Image of a Black Hole Revealed
Scientists from the Event Horizon Telescope project unveiled the first-ever image of a black hole located at the center of the M87 galaxy. This groundbreaking achievement was the result of a global collaboration of over 200 researchers working in various institutions worldwide. The image revealed a bright ring formed by light bending around the black hole's gravitational pull, providing significant evidence of the existence of black holes and confirming theories of general relativity.

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.

NASA confirmed that its Voyager 1 probe has officially entered interstellar space, making it the first human-made object to do so. Launched in 1977, Voyager 1 was designed to study the outer planets of our solar system. As of September 12, 2013, it crossed the heliopause, the boundary where the solar wind from the Sun slows down and merges with the interstellar medium. This milestone marks a significant achievement in human exploration and understanding of the cosmos.

J. Robert Oppenheimer and his student Hartland Snyder revealed the Oppenheimer–Snyder model, which elegantly articulated how black holes could form within the framework of general relativity. This groundbreaking work illustrated the gravitational collapse of massive stars, providing a theoretical basis for the existence of black holes, a topic that had tantalized physicists for years. Their collaborative research marked a significant advancement in modern astrophysics, bridging the gap between theoretical predictions and astronomical phenomena.

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.
