Looking For Advanced Aliens? Search For Exoplanets With Large Coal Deposits

The combustible sedimentary rock, better known as coal, was not only crucial to the onset of advanced technology here on earth, but it should also be key to the development of advanced E.T.s residing on any given exoearth. from Universe Today https://ift.tt/3ztsaQ0 via IFTTT

The Collaboration that Brought you the First Image of a Black Hole Just Released Photos of its Massive Jet

Recently published data from the Event Horizon Telescope (EHT) of the galaxy Messier 87 facilitate new insights into the direct environment of the central supermassive black hole. Measured differences in the radio light on different spatial scales can be explained by the presence of an as of yet undetected jet at frequencies of 230 Gigahertz at spatial scales comparable to the size of the black hole. The most likely location of the jet base is determined through detailed modeling. from Universe Today https://ift.tt/fPLtzAa via IFTTT

Is the Universe Older Than We Think? Part 4: The Changing Lambda-scape

Isn’t the FLRW metric way generic? It lays out the basic assumptions and tells us how the universe should behave, but it doesn’t say WHAT the universe is made of. from Universe Today https://ift.tt/FLpdNlO via IFTTT

The Dirty Afterlife of a Dead Satellite

Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people's lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century - satellite megaconstellations. from Universe Today https://ift.tt/soEerLS via IFTTT

The "Little Red Dots" Observed by Webb Were Direct-Collapse Black Holes

The discovery by JWST of a substantial population of compact "Little Red Dots" (LRDs) presented astronomers with a major mystery. By reproducing their spectra with simulations, a team argued that they were Direct Collapse Black Holes (DCBHs). from Universe Today https://ift.tt/h2xgSrA via IFTTT
