6 OCT. 2024 · On October 6th, 1995, a groundbreaking discovery was made that forever changed our understanding of the universe and the possibility of life beyond Earth. On this date, Michel Mayor and Didier Queloz, two Swiss astronomers, announced the detection of the first exoplanet orbiting a main-sequence star, 51 Pegasi.
51 Pegasi b, affectionately nicknamed "Bellerophon" after the Greek mythological hero who tamed Pegasus, is a gas giant about half the size of Jupiter. However, what makes this planet truly remarkable is its proximity to its host star. Orbiting at a distance of only 7.5 million kilometers (4.7 million miles), 51 Pegasi b completes a full orbit in just 4.2 Earth days! This discovery challenged the prevailing theories of planetary formation and showed that planets can exist in a wide variety of configurations.
The detection of 51 Pegasi b was made using the radial velocity method, which measures the wobble of a star caused by the gravitational pull of an orbiting planet. Mayor and Queloz's discovery kicked off a new era in astronomy, one focused on the search for exoplanets and the potential for life in the universe.
Since that fateful day in 1995, over 5,000 exoplanets have been confirmed, with many more candidates awaiting verification.

5 OCT. 2024 · On October 5th, 1923, Edwin Hubble made a groundbreaking discovery that forever changed our understanding of the universe. While observing the night sky through the 100-inch Hooker Telescope at the Mount Wilson Observatory in California, Hubble identified a Cepheid variable star within the Andromeda Nebula (now known as the Andromeda Galaxy).
Cepheid variable stars are a special type of star that pulsates with a regular period, and their brightness is directly related to their pulsation period. This relationship allows astronomers to calculate the distance to these stars with great accuracy. Hubble's discovery of a Cepheid variable in the Andromeda Nebula allowed him to determine that it was located far beyond the boundaries of our Milky Way galaxy, which was a revolutionary idea at the time.
This revelation shattered the long-held belief that the Milky Way encompassed the entire universe. Hubble's finding provided the first concrete evidence that the universe extended far beyond our own galaxy and that countless other galaxies existed in the vast expanse of space.
Hubble's discovery opened the door to a new era of cosmology and extragalactic astronomy. It laid the foundation for future discoveries, such as the expansion of the universe and the Big Bang theory. Today, astronomers continue to build upon Hubble's work, exploring the depths of the universe and unraveling its mysteries.
So, the next time you look up at the night sky and spot the faint, fuzzy patch of the Andromeda Galaxy, remember the incredible discovery made by Edwin Hubble on this day in 1923. It's a testament to the power of human curiosity and the wonders that await us in the cosmos.
