Comets and interstellar objects could export Earth's life to the Milky Way

For over a century, proponents of panspermia have argued that comets, asteroids, spaceborne dust, and planetoids are spreading life in our galaxy. However, in recent years, scientists have argued that this type of distribution can go beyond star systems and be intergalactic. Some have even proposed fascinating new mechanisms for how this distribution could take place. For example, it is …

Will the Milky Way become gaseous? A new study says yes

An excessive amount of gas flowing into the Milky Way has been discovered by astronomers – though the reason for the phenomenon remains a mystery. According to NASA's Hubblesite, data comes from about 10 years ago The Hubble Space Telescope shows more gas coming in than came out, said Andrew Fox, astronomer and lead author of an upcoming study for …

Why does the Milky Way become so gaseous?

Astronomers have discovered a strange excess of gas in the Milky Way galaxy. Using 10-year data from NASA's Hubble Space Telescope, the team of astronomers concluded that more gas is flowing into and out of our galaxy. Instead of a balance between gas entry and exit, there is a significant imbalance, although the team behind this finding has not yet …

The Milky Way is a thief – BGR

We often think of our home galaxy, the Milky Way, as a self-contained collection of stars, planets, gas and dust. Sure, sometime in the distant future, it will penetrate directly into the neighboring Andromeda galaxy, but right now the Milky Way is as good as a cool off, right? Not so fast. A New Research Effort to Investigate the Movement …

Secret when Hubble Milky Way raids finds intergalactic bank accounts

This illustration shows the gas recycling of the Milky Way above and below the star disc. Hubble observes the rising and falling of invisible gas clouds with his sensitive Cosmic Origins Spectrograph (COS) instrument. The spectroscopic signature of light from background quasars shining through the clouds provides information about their movement. Quasar light is red-shifted in clouds that shoot up …

The NASA photo shows the Milky Way galaxy center in striking detail

The center of the Milky Way is a crowded hub of millions of stars, surrounded by ultraviolet radiation and X-rays, swirling around a black hole as massive as 4 million suns. A shell made of dust and gas It's hard to see all of these activities, but NASA's NASA's Spitzer Telescope cut through the fog in 2006 with infrared sensors, …

The Milky Way attacks intergalactic "bank accounts," says Hubble

This figure shows the gas recirculation of the Milky Way above and below its star disk. Hubble observes the rising and falling of invisible gas clouds with his sensitive Cosmic Origins Spectrograph (COS) instrument. The spectroscopic signature of light from background quasars shining through the clouds provides information about their movement. Quasar light is red-shifted in clouds that shoot up …

Milky Way galaxy's center exploded 3.5M years ago

The Milky Way galaxy is home to all life as we know it, but about 3.5 million years ago, something strange and "dramatic" happened to it – a massive explosion in its center. According to a new study, the galaxy was hit with an energy flare, near an enormous black hole. Ultimately, the impact of the flare was felt 200,000 …
