Mars is the second smallest planet in our solar system and the fourth planet from the sun. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.-“>Mars for billions of years.”
Superflare erupts
Notsu explains that coronal mass ejections often occur right after a star releases a glow, or a sudden burst of bright radiation that can extend far into space.
However, recent research suggests that on the Sun, this sequence of events may be relatively quiet, at least as far as scientists observe. In 2019, for example, Notsu and company published a study which suggests that young sun-like stars in nearby galaxies appear to be experiencing multiple superplanets — like our own solar flares but tens or even hundreds of times more intense.
Such superflares, in theory, could also occur in Earth’s sun but not often, perhaps once every few thousand years. However, this piqued the Notsu team’s curiosity: Could a superflare also emit that much coronal mass?
“Superflares are much larger than the flares we see from the sun,” said Notsu. So we suspect it will also result in much larger mass ballistics. But as of now, this is just a guess.”

To find out, the researchers set their sights on EK Draconis. Notsu explains that the curious star is about the same size as our sun, but at only 100 million years old, it is relatively young in the cosmic sense.
“This is what our sun looked like 4.5 billion years ago,” said Notsu.
Researchers observed the star for 32 nights in winter and spring 2020 using

life, which is called the “fuse eruption” phase. But even so, it was a monster moving at a top speed of about a million miles per hour.
This may not bode well for life on Earth either: The team’s findings suggest that the Sun can also carry out such violent states. But don’t hold your breath—as with superplanets, ejections of supercoronal masses will likely be rare around the sun in a few years.
However, Notsu notes that massive mass emissions may have been more frequent in the early years of the solar system. In other words, the massive ejection of the corona could help shape planets like Earth and Mars into what they are today.
“The atmosphere of Mars is currently very thin compared to Earth’s atmosphere,” said Notsu. “In the past, we thought that the Martian atmosphere was much thicker. The coronal mass ejection could help us understand what happened to the planet over billions of years.”
