Arthur T Knackerbracket has processed the following story:

The M87 galaxy is monstrous.

It contains several trillions of stars, compared to our Milky Way's hundreds of billions. And the supermassive black hole at its center is shooting an outstretched beam of energy into space. The Hubble Space Telescope, operated by NASA and the European Space Agency, has captured a new image of this energetic cosmic event, which produces a beam of superheated gas 3,000 light-years long (a single light-year is nearly 6 trillion miles).

NASA calls this jet "blowtorch-like," and it seems to be triggering many stars near its trajectory to erupt.

"We don't know what's going on, but it's just a very exciting finding," Alec Lessing of Stanford University, who led the research into the finding, said in an agency statement. "This means there's something missing from our understanding of how black hole jets interact with their surroundings."

In the Hubble telescope image below, the colossal elliptical galaxy M87, which is shaped like a giant egg, looks like "a translucent, fuzzy white cotton ball," ESA explained. The jet, as you can see, is the wavy blue beam blasting out from the galactic core, home to the supermassive black hole (it has the mass of 5.4 billion suns).

As the jet shoots through the galaxy, astronomers suspect it's triggering a type of stellar explosion called a "nova." These eruptions happen in double-star systems with an aging star — which is bloated and shedding its layers — and a white dwarf star, which is the hot core of a sun-like star that has shed its mass. The swollen star dumps material (hydrogen) on the white dwarf. "When the dwarf has tanked up a mile-deep surface layer of hydrogen that layer explodes like a giant nuclear bomb," the agency explained. And then the gradual process renews.

    Whoever controls this is just warning us to stay away or else they can redirect the beam straight at us.
