1.- Apple becomes the first company to reach a stock market value of $3 Trillion :

In January, Apple's value briefly hit the $3 trillion mark, making it the first publicly traded company to do so. Its value has since declined, as it and other companies face a skittish economy still reeling from the effects of Covid-19 pandemic and record inflation.

Apple was also the first company to be valued at $1 trillion, in 2018, and $2 trillion, in 2020.

2.- Scientists pinpoint how star formation in our Galaxy began.

Scientists can explain for the first time what triggered the formation of stars in the Milky Way, according to a paper published in Nature in January.

Researchers say a chain reaction of supernovae about 14 million years ago led to the creation of a 1,000-light-year-wide bubble, at the center of which lies our galaxy.

Though scientists knew how this bubble existed, they recently discovered that all the local star forming regions sit on its surface, because the chain reaction pushed away the dust and gas needed to produce new stars to the bubble's edges.

3.- Microplastics are detected in human blood.

A study published in March in Environment International found microplastics in human blood.  About half of the participants in the study had polyethylene terephthalate - a polymer used in water bottles and food packaging, among other everyday items - in their bloodstream.

Scientists have previously established that people are exposed to microscopic particles of plastic through the food they eat, the water they drink and the air they breathe.

4.- An ice shelf collapses in East Antarctica.

The Conger ice shelf collapsed in mid-March, the first such collapse in the eastern part of Antarctica since satellites started recording activity there in 1979.

The collapse of the 450-square-mile stretch of ice occurred sooner than expected, according to experts, and in a part of the continent that is considered less vulnerable to the effects of climate change.

5.- Scientists capture an image of the Milky Way's Black Hole

In May, scientists unveiled the first image of Sagittarius A*, a black hole at the center of our galaxy. It was the result of an international effort known as the Event Horizon Telescope Project

In 2019, the same team of scientists unveiled the first image of a black hole at the center of the galaxy M87, which is 1,500 times larger than Sagittarius A*.
