Studying the stars with machine learning
To keep up with an impending astronomical increase in data about our universe, astrophysicists turn to machine learning.
How’s it going, LIGO?
The Laser Interferometer Gravitational-Wave Observatory has a new digital assistant.
Mapping the universe in 3-D: Fermilab contributes to the Dark Energy Spectroscopic Instrument
DESI, an instrument to help scientists get to the bottom of the dark energy mystery, is getting a little help from Fermilab.
This new satellite is on a mission straight out of ‘Star Trek’
From CNN, July 12, 2018: Fermilab scientist Don Lincoln discusses the Transiting Exoplanet Survey Satellite, which was launched atop a SpaceX Falcon 9 rocket. Its extended goal is to identify approximately 20,000 planets around nearby star systems.

How an advanced civilization could stop dark energy from preventing their future exploration
From Universe Today, June 20, 2018: A Fermilab astrophysicist recently conducted a study that indicates how a sufficiently advanced civilization might be able to harvest Local Group stars and prevent them from expanding outward.
Study reveals reason aliens may be snatching stars and caging them in megastructures
From Russia Today, June 21, 2018: Expansion of the universe, thought to be further accelerated by dark energy, is flinging matter apart, while galaxies are being pushed away from each other. This is a challenge alien technologies will have to deal with in order for them to survive, Fermilab’s Dan Hooper writes in a new study.
To combat an expanding universe, aliens could hoard stars
From Science News, June 19, 2018: Fermilab physicist Dan Hooper proposes that, to offset a future cosmic energy shortage caused by the accelerating expansion of the universe, a super-advanced civilization could pluck stars from other galaxies and bring them home. It’s a far-out idea, tackling a dilemma in a future so distant that human beings can hardly fathom it: 100 billion years from now, each neighborhood of the universe will be marooned as if on a cosmic island, with resources from the rest of the universe inaccessible.
