108. The Hubble Tension
Year Found: 2021
Who Found It: Edwin Hubble
Location: N/A
It is no secret that Hubble’s Tension from 2021 has generated a lot of discussion and controversy in the scientific world; it is still a contentious issue among experts in the area. Two conflicting estimation rates have different points of view when the expansion of the cosmos itself is the subject of discussion.

With the way things are going right now, the Hubble tension is going to be an extremely intriguing riddle mystery. It may be some time before the problem has been resolved as ongoing work continues to try to refine both the early and late timeframes of the Hubble constant.
109. 79 Moons Around Jupiter
Year Found: 1610
Who Found It: Galileo Galilei
Location: Area around the planet Jupiter
Thus far, there are 53 moons around the gas planet of Jupiter that have been officially named, leaving 16 moons unnamed and waiting for a name for them to be assigned. Even though Galileo Galilei was the first one ever to take note of and observe the first four moons, since 1999 there have been 61 moons discovered.

For example: compared to the Earth’s moon, Galileo Galilei’s four first discovered moons named Europa, Callisto, Io, and Ganymede have been measured and have been noticed to be way larger, but the remaining amount of 74 moons appear to be way smaller, though.
110. A Map Of The Milky Way
Year Found: 2013
Who Found It: Gaia Spacecraft – Gerry Gilmore
Location: The Milky Way
It is an undeniable fact that every discovery about the Milky Way in general has represented a considerable step forward when it comes to the discovery of the Universe in the context of astronomy and cosmology in particular.

Because the Milky Way is 13.6 billion years old and consists of around 100 billion stars, it is more than interesting to observe the possibility of viewing a three-dimensional view of it in the form of a map which has been provided in 2013 by Gerry Gilmore from Gaia as very unique.
111. Cosmic Temperature Independently Measured
Year Found: 2004
Who Found It: A group of authors
Location: The area of the Cosmos
The instrument for the measurement of the microwave level background of the Cosmos is called ARCADE, which stands for The Absolute Radiometer For Cosmology, Astrophysics, And Diffuse Emission, and it uses narrowband cryogenic radiometers for the comparison of the sky to external full-aperture calibrators.

ARCADE is using a novel open-aperture design, which has no windows or other possibly warm objects between the antenna it has and the sky, allowing it to take measurements more precisely than its predecessor forms.
112. Rogue Stars
Year Found: 1997
Who Found It: The Hubble Telescope
Location: Outside of the Galaxy
Compared to stars that are known to be present in the area of a galaxy and bound to it, there is another interesting phenomenon when it comes to the location of stars. It should be noted that some Stars appear not to be bound to a specific galaxy, and they have been named – Rogue Stars.

The first time these stars have been noticed was in the year of 1997, and they have been spotted via a Hubble telescope. There exists a high probability that these stars have been originally born within a certain galaxy, though it is still pretty much unclear how they ended out being outside any galaxy.
113. Water Jets Over Enceladus
Year Found: 2015
Who Found It: NASA – Cassini
Location: Enceladus
In 2015, Cassini’s mission maneuver aimed to collect and reveal possible data to help with the very determination about the possible prospects which could support the idea of life existing within its ocean. In previous research, Cassini’s spacecraft has already helped with revealing other data about Jupiter’s moon.

There has been a massive discovery that implied that there is hydrothermal as well as geological activity, which includes various kinds of basic elements which could secure all of the necessary ingredients needed for life.
114. The Cigar Galaxy
Year Found: 1774
Who Found It: Johan Elert Bode
Location:M82 – The Cigar Galaxy
M82, which is also known as the Cigar galaxy, is significant for its star formation activity and glows brightly at infrared wavelengths. The Cigar galaxy interacts gravitationally with its nearby galaxy, M81, which ultimately resulted in a starburst, and that is best described as an exceptionally high rate of star formation.

The galactic wind that is the result of these stars’ radiation and energetic particles compresses sufficient gas to create millions of additional stars. The galaxy’s rapid star formation rate will reach a moment in time when it reaches its self-imposed limit. Star material will be eaten up or destroyed if a star formation accelerates too quickly.
115. A Growing Galactic Metropolis
Year Found: 2007
Who Found It: A group of astronomers
Location: COSMOS-AzTEC3
2011 saw the occurrence of an interesting and entertaining event. A team of astronomers using the Spitzer space telescope discovered the COSMOS-AzTEC3 galaxy cluster, which is located in a very distant galaxy cluster. For this group of galaxies’ light to reach Earth, it had to travel for even more than 12 billion years.

This very specific kind of object, which is known as a proto-cluster, is believed by astronomers to have evolved into modern galaxy clusters, which are groupings of galaxies held together by a gravitational field. At the time, COSMOS-AzTEC3 was the most distant proto-cluster ever found. It has given scientists a clearer understanding of how galaxies have developed and changed throughout the universe’s historical memory.
116. Comet 67P/Churyumov–Gerasimenko
Year Found: 1969
Who Found It: Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko
Location: Comet 67P/Churyumov–Gerasimenko
Originally from the Kupier-belt, the Comet 67P/Churyumov–Gerasimenko is a member of the Jupiter family. First found in 1969 by two Soviet astronomers – Svetlana Ivanovna Gerasimenko and Klim Ivanovych Churyumov, and these two scientists also named the comet after themselves.

Exhilarating things happened during Rosetta’s investigation of Comet 67P/Churyumov-Gerasimenko, from the time the spacecraft emerged from hibernation in 2014 and tried to approach the comet’s duck-shaped surface to its eventual impact with the surface in 2016.
117. Himiko
Year Found: 2009
Who Found It: Masami Ouchi
Location: Himiko
The well-known Lyman-alpha blob which Masami Ouchi from the Carnegie Institution in Pasadena, California has named after the 3rd-century Japanese shaman queen Himiko is the constellation Cetus, around 12.9 billion years away from the planet Earth. Himiko is half the size of the Milky Way.

Something that makes Himiko very interesting and special is the fact that it represents the by-now-defined primordial Lyman-alpha blob, which makes it the oldest ever known Lyman-alpha blob ever discovered in history.
118. Fast Radio Bursts (FRB)
Year Found: 2007
Who Found It: Duncan Lorimer and David Narkevic
Location: N/A
In 2007, David Narkevic and Duncan Lorimer started looking for pulsars in historical data from the Parkes radio telescope’s archives in Australia. At the time, they had no idea that they were about to go through an extraordinary experience and make one of the most exciting discoveries in years.

They made the incredibly important finding of the Lorimer Burst, which was noted in the Parkes data in 2001. The Lorimer burst, which was the first fast radio burst (FRB) to be recognized and had been recorded in the Parkes data in 2001, has been found in this instance.
