New Delhi: 2021 was a great year for pioneering scientific research and a lot of important work was done in the field of science, especially space exploration, astronomy and biological research. The whole year has been about news like the race for space tourism is heating up with many commitments made at the Climate Change Conference in Glasgow.
The following is a list of the most important scientific news and research work completed in 2021:

1. Launching the most powerful space observatory ever built

The launch of the James Webb Space Telescope (JWST), the most powerful space observatory ever built, is not only the biggest science news of the year, but also one of the biggest in several years. After years of waiting, JWST, an international collaboration between NASA, the European Space Agency and the Canadian Space Agency, blasted off into space on Christmas Day. JWST, also known as Webb, is the successor to the Hubble Space Telescope that will reveal the secrets of the universe, looking at the oldest stars and galaxies.

2. Einstein’s theory of general relativity has faced its toughest test yet

Researchers from the University of East Anglia (UEA) helped conduct a 16-year experiment to challenge Einstein’s general theory of relativity, by looking at the stars. A pair of extreme stars called pulsars were observed by seven radio telescopes around the world, as part of the study. The scientists used their observations to challenge Einstein’s most famous theory, which states that gravity is a curvature or distortion of spacetime, and that gravity affects spacetime.
The study revealed new relativistic effects that were observed for the first time.

3. The sun is in turmoil

This year, there have been several instances of powerful bursts of radiation, or solar flares, from the surface of the Sun.
In early November, a strong G3 geomagnetic storm occurred, which was caused by solar flares. This led to the appearance of the aurora borealis in the low latitudes of the Earth.
In late October, a sunspot unleashed a Class X1 solar flare, setting off a massive tsunami of plasma that moved across the entire solar disk. Plasma and magneto particles blew out the sunspots on the same day, expelling the coronal mass ejection (CME).
The turbulence experienced by the Sun in 2021 is surprising because the star had a weaker solar cycle in the past decade, compared to the previous decade, according to a study by Indian scientists. This resulted in weaker solar storms during Solar Cycle 24, which lasted from 2008 to 2019. Also, the Sun was the weakest in 2019.
In a new study, Indian astronomers have found that the changing structure of the magnetic field on the surface of the sun determines whether the sun emits a solar flare or a solar flare, an understanding believed to be useful in improving solar weather forecasts.

4. The Missing Case of Blue Space Corporation’s Jeff Bezos v NASA

Blue Origin sued NASA in August over a $2.9 billion lunar landing contract that NASA awarded to Elon Musk’s SpaceX for the upcoming Artemis mission. In November, the US Court of Federal Claims ruled against Blue Origin. In a statement, NASA said that work with SpaceX will resume “as soon as possible.”

5. Space tourism race as temperatures rise

2021 was a very important year for space tourism. Seven space tourism missions have been completed. This mission included the SpaceX Inspiration4 mission, the world’s first entirely civilian mission to orbit, and the Soyuz MS-20 mission, which was the first self-financed space tourism mission to the International Space Station (ISS) in a decade.
William Shatner, Captain Kirk of Star Trek, became the oldest man to go into space in October.
Most interesting is that the first feature film was shot in space this year. A Russian camera crew stayed aboard the International Space Station for 12 days to shoot parts of a movie called “Fyuzov”, meaning “challenge”.

6. Strange radio waves are emitted from the center of the galaxy

In October, astronomers detected strange radio signals coming from the direction of the center of the Milky Way. The new radio waves detected did not match any of the previously known patterns.
One of the researchers said that the most unusual thing about the new signal is its “very high polarization,” meaning that the light oscillates in only one direction, but that direction rotates over time.

Astronomers believe these unusual signs could point to a new class of stellar objects.

7. Announcing the plans for the commercial space station

In October, Blue Origin and Sierra Space announced their plans for a developed, owned and commercially operated space station to be built in low Earth orbit. Blue Origin called the space station “Orbital Reef” and claimed it would accommodate up to 10 people by the second half of the decade.
Space company Nanoracks will also develop its own commercial space station, which it calls “Starlab,” and Northrop Grumman has not yet named its space center. NASA awarded contracts worth millions to the three private companies.

8. Commitments made at COP26 in Glasgow, Scotland

The 26th United Nations Climate Change Conference, commonly referred to as COP26, took place in Glasgow, Scotland in the United Kingdom from October 31 to November 12. COP 26 concluded with 197 countries agreeing to a new climate agreement: the Glasgow Climate Pact, to keep 1.5°C alive and finalize the 2015 Paris Agreement.
Countries have made collective commitments to reduce methane emissions, align the finance sector with net zero by 2050, to halt and reverse deforestation, abandon the internal combustion engine, accelerate coal phase-out, and end international financing for fossil fuels, to name a few.

In September, scientists from Washington University in St. Louis found new evidence supporting the idea that America’s first civilization was made up of “advanced engineers.” Evidence suggests that Native Americans or Native Americans were highly skilled engineers who were able to build massive earthen structures within a few months, and sometimes, even weeks. One researcher claimed that these early earthworks have solidified for more than 3,000 years without significant failure or erosion.

One example is the Poverty Point World Heritage Site in Louisiana, United States, which consists of 72-foot-high earthen mounds and mounds built by hunter-gatherers about 3,400 years ago.

In 2020, scientists announced the discovery of a strange object that they had stumbled upon by chance. This year they discovered more about the object, a “brown dwarf” nicknamed “The Accident”. the incidentAnd It was also found by absolute luckAnd It is unique in that it is unlike other brown dwarfs (more than 2,000 of them) that have been detected so far in the Milky Way.
