The year 2020 is a pronounced year for scientists studying our universe. Despite the impact of the COVID-19 pandemic, physicists have still found time to carry out their research. Some of the top stories in physics in the year 2020 are follows:

Fast Radio Bursts (FRBs) are fast, high-powered, frequency-hopping radio signals that coming from all over the sky, which makes it complicated to identify their origin. However finally, in the year 2020, astronomers found an FRB source in our own cosmic backyard. Further studies shows that an exotic star known as a Magnetar which sometimes burp out a tremendous amount of pent-up energy that appears to Earth as a quick explosion of radio emission.

The Red Planet Mars has been teasing astronomers for decades on the dynamic question of whether it's home to any liquid water at all. Astronomers care about it because, where there's water, there's a probability for potential home for life. Earlier this year 2020, astronomers claimed that there isn't just one, but four lakes of liquid water on Mars. They're extremely
salty - more like a briny sludge than something to take a dip in and buried under a mile of frozen carbon dioxide at the southern polar cap. Through some scientists had claimed about it, but everyone is not convinced about it.

The year 2020 was surely a lucky year of our solar system. Three independent spacecraft have fruitfully acquired samples and sent them on their way back to Earth. NASA launched its OSIRIS-REx mission to the asteroid Bennu, which collected lots of material that its sample container leaked. The Chinese Chang'e 5 lander went on a mission to the moon, managing to launch a sample back to the Earth before the lander broke down. Also, the Japanese Hayabusa2 mission took a poke at the asteroid Ryugu and landed the material securely back to the Earth.

The claims of solid evidence for life in the cloud tops of Venus, an otherwise hellhole of a world was mainly based on phosphine, a peculiar (and stinky) chemical emitted on the Earth by anaerobic bacteria. Scientists proposed that Venus would need a large population of airborne microbes due to abundant phosphine in the atmosphere. But unfortunately, further analysis reduced the observed amount of the stinky stuff, and even in some analyses, removed it overall as just additional noisy signal.

The Covid-19 pandemic is an on-going pandemic of Coronavirus disease 2019 cause by Severe Acute Respiratory Syndrome Coronavirus. Within a couple of months the novel coronavirus has devastated and effects peoples all over the world. Vaccine is the most powerful weapons to fight with the Covid-19 virus. Although many labs postponed basic research in March 2020 due to the pandemic, some physical science facilities remained open to conduct research on the novel coronavirus. The recent vaccines for Covid-19 target a very specific portion of the virus, a "spike" protein that it uses to attack our cells. One of the leading steps in the war against Covid-19 was to identify and map that protein. In May 2020 editor David Kramer examined by using a physics-based technique called cryogenic electron microscopy work at light sources around the world to determine the structure of the virus. Using this map, drug makers could target this feature of the virus for making Covid-19 vaccine.
