How Beatriz Villarroel's claims fared when checked

Our assessment

The site's assessmentChecked 29 Sep 2026

A real, credentialed, prize-recognized astronomer whose core VASCO statistical claim (a population of brief, real, star-like transients on old photographic plates that current surveys don't reproduce) is a live, peer-reviewed, actively contested question in mainstream astronomy, not settled science and not debunked pseudoscience. Her personal leap from 'artificial, reflective near-Earth objects' to public support for crash-retrieval and non-human-biologics claims is a separate, much less credentialed extension of her actual research.

Credentials

Verified credentials

  • PhD in Astronomy, Uppsala University; MS Physics, Uppsala University
  • Assistant Professor, Nordic Institute for Theoretical Physics (Nordita), Stockholm University, current position per Stockholm University's own faculty profile
  • Founder/leader of the VASCO (Vanishing & Appearing Sources during a Century of Observations) project since 2017 and its associated citizen-science and EXOPROBE projects
  • 2021 L'Oréal-UNESCO For Women in Science national prize (Sweden), for the VASCO project
  • 2022 L'Oréal-UNESCO For Women in Science International Rising Talents award (first Swede to receive it; top 15 female early-career scientists internationally)
  • Multiple peer-reviewed first- or co-authored publications on the VASCO transient dataset, including a July 2025 published response (Villarroel, Solano, Marcy) to the Hambly & Blair critique, in a real, ongoing peer-reviewed back-and-forth

Unverified or disputed credentials

  • 'PhD student in astronomy as of 2016' (per library/people.json, from her own account in the corpus video), consistent with an Uppsala PhD completed sometime after 2016 and her VASCO project founding date of 2017; not independently dated to an exact defense year in this pass
  • No institutional affiliation is stated in the corpus video itself (flagged there as a gap); this dossier confirms she is affiliated with Nordita/Stockholm University, resolving that gap
  • Co-founder of a public 'European Crash Retrieval Initiative', real per the corpus video's own credentials_claimed list, but this dossier found no independent, non-self-reported source describing this initiative's scope, membership, or scientific standing; treat as an unverified extension of her public profile well outside her astronomy credential

Top Astronomer: UFOs Are STILL Here

  • Unverified0:00Secondhand

    Villarroel states she personally believes that tic-tac craft, non-human biologics, and interdimensional-being claims are true, based on trusting unnamed 'really credible people' who discuss crash retrievals, while stating that no such evidence is directly accessible to her as a scientist.

    I believe it's true... there's I believe that what is being said there is most I mean I believe it's true

  • Unverified3:05

    The hypothesis that massive stars can collapse directly into a black hole without a visible supernova motivated Villarroel's original 2016 search for vanishing stars.

    there's a a class of uh like um uh massive stars that are believed that they might be able to collapse into a black hole without emitting any supernova

  • Unverified9:13Unsourced

    Villarroel states that when she and two bachelor's students first tested the vanishing-star search on about 1% of a US Naval Observatory sample in 2016, the full network/project did not yet exist; it was formally organized with two senior scientists in 2017.

    in 2016 I had together with two bachelor students tried to do a small search in a like 1% of the sample... but then they said okay now we need to do the whole sky

  • Supported11:15Official document

    VASCO's automated pipeline analyzed about 600 million objects across the northern hemisphere comparing 1950s Palomar plates to modern surveys and found zero genuinely vanishing stars.

    we actually went through something like uh 600 million objects... and we found zero vanishing stars

    Our check Confirmed: Villarroel's VASCO project, using an automated cross-matching pipeline (associated with Enrique Solano) compared roughly 600 million objects from the USNO B1.0 catalog against Pan-STARRS DR1, flagging about 150,000 candidates lacking a modern counterpart (about 106,000 of them in the northern hemisphere). Despite this large-scale search, the project's original goal of finding a genuinely vanishing star (one that disappears with no trace and no plausible mundane cause) was not achieved; no such object was confirmed.

  • Unverified13:18Single sensor

    While searching for vanishing stars, VASCO found one plate image containing nine star-like transient objects appearing and vanishing simultaneously within a small patch of sky.

    one of these images had nine objects appearing and vanishing at the same time but in a small image

  • Unverified15:21Official document

    Across large samples, VASCO transients show a statistically narrower, sharper brightness profile than real stars of matched magnitude, consistent with a very short flash rather than a steady point source.

    if you take a big sample of these transients and you compare to a big sample of the stars you see that they are slightly... sharper and more narrowed

  • Unverified22:31Multi sensor

    Villarroel's team pointed a large optical telescope in the Canary Islands, using a colleague's rapid-light-burst detector technology, at transient locations to test for active laser/artificial-signaling activity, and found nothing, which she says takes that hypothesis 'totally off the table.'

    we actually even use the largest telescope in the world, optical telescope in the world in Caner Islands, pointed at those things and we found nothing there. So that hypothesis is is totally off the table

  • Unverified26:34Official document

    VASCO transients show a statistically significant deficit specifically within the geometric shadow of the Earth (42,000 km altitude, ~8.7 degree radius), which Villarroel calls her strongest single piece of evidence because atmospheric scattering of cosmic rays could not track that precise geometry.

    the earth shadow def the visit I think is really beautiful to work with and uh I mean we see a big deficit of this transis in the earth shadow
