With the discovery during the latter half of the twentieth century of more objects within the solar system and large objects around other stars, dispute arose over what should constitute a planet.

«If there is water in Kuiper belt - like objects around other stars, as there now appears to be, then when rocky planets form they need not contain life's ingredients,» said Siyi Xu, the study's lead author, a postdoctoral scholar at the European Southern Observatory in Germany who earned her doctorate at UCLA.

In a few thousand years of recorded history, we went from dwelling in caves and mud huts and tee - pees, not understanding the natural world around us, or the broader universe, to being able to travel through space, using reason to ferret out the hidden secrets of how the world works, from physics to chemistry to biology, we worked out the tools and rules underpinning it all, mathematics, and now we can see objects that are almost impossibly small, the very tiniest building blocks of matter, (or at least we can examine them, even if you can't «see» them because you're using something other than your eyes and photons to view them) to the very farthest objects, the planets circling other, distant stars, that are in their own way, too small to see from here, like the atoms and parts of atoms themselves, detected indirectly, but indisputably THERE.

Hubble now enters a phase of full science observations ranging from studying the population of Kuiper Belt objects at the fringe of our solar system to surveying the birth of planets around other stars.

The VLA data were used to track the orbit of the smaller Southern star around the larger Southern object, presumed to be a pair of stars orbiting each other closely.

The star exhibits weird fluctuations in its brightness, leading a few astronomers to propose — among many other ideas — that maybe a swarm of alien megastructures is orbiting around the object.

«This allowed us to measure the time it takes for the black hole and the donor star to rotate around each other, which is 64 days, and to model the velocity of the two objects and the shape of the orbit,» Soria said.

The halos around quasars — the brightest and the most active objects in the universe, they are galaxies formed less than 2 billion years after the Big Bang; they have supermassive black holes in their centers and consume stars, gas, interstellar dust and other material at a very fast rate — are made of gas known as the intergalactic medium and extend for up to 300,000 light - years from the centers of the quasars.
