NASA Confirms Rare Phenomenon as Three Black Holes Consume Giant Stars—and this ain’t sci-fi, folks. Three separate events have shown supermassive black holes in distant galaxies shredding giant stars—each star weighing in at 3 to 10 times the Sun’s mass—with gargantuan flares lasting months. Astronomers call them extreme tidal disruption events (TDEs), and they’re lighting up what used to be cosmic darkness.
A team of scientists, using NASA’s Swift Observatory, ESA’s Gaia mission, Zwicky Transient Facility (ZTF), NEOWISE, and ground-based telescopes, unveiled a breathtaking space discovery in 2025. As someone whose heart beats for space stories and guided by Indigenous respect for the cosmos, I see this as powerful proof that listening to the universe transforms us. This find—a rare cosmic event—connects kids, families, and researchers, inspiring hope and care. Here’s a simple, heartfelt guide to what happened, why it matters, and where this journey is headed.
The team spotted a gamma-ray burst (GRB), a brilliant flash from a collapsing star 13 billion years ago, using Swift’s X-ray sensors and ZTF’s wide-field scans. Gaia mapped its precise location, while NEOWISE and telescopes in Chile confirmed it as one of the earliest bursts ever seen.

Three recent tidal disruption events (TDEs), including the dazzling “Barbie” and two Gaia-triggered flares, revealed hidden black holes in 2025, casting a cosmic spotlight on the universe’s secrets. With upcoming surveys like LSST and eROSITA, plus gravitational-wave detection, star-eating black holes are becoming everyday tools for exploring the stars. This isn’t just science—it’s a heartfelt way to read the universe’s story, connecting kids, communities, and scientists with wonder and hope. Here’s a simple, human-focused guide to their meaning.
TDEs happen when a star gets too close to a black hole and is torn apart, creating a brilliant flare. “Barbie,” spotted by ESA’s Gaia mission in 2024, lit up a galaxy 1 billion light-years away, revealing a previously unknown black hole []. Two other flares, detected by Gaia and ground telescopes in Chile, showed black holes devouring stars in distant galaxies.
What Went Down in These TDEs
“Barbie” – ZTF20abrbeie (2020)
ZTF spotted a bright flare in a galaxy center—Swift confirmed it was a tidal rip-apart and consumption. It burned bright for months. (nature.com)
Gaia’s 2016 & 2018 Discoveries
Gaia flagged two unexpected brighteners; Swift and NEOWISE stepped in to verify—they, too, were black holes tearing apart stars.
Why These Discoveries Matter

Cosmic Light Shows
Each flare outshines hundreds of supernovae, releasing jaw-dropping stellar energy in a cosmic fireworks display.
Population & Expectations
Current detection rate is around 10 TDEs per year, matching optical surveys. X-ray surveys (eROSITA) show about 1.2×10⁻⁵ per galaxy yearly.
The Next Chapter—LSST, eROSITA & Gravitational Waves
Rubin Observatory’s TDE Boom
LSST is expected to discover up to 1,000 TDEs annually—some simulations even suggest 35,000–80,000 over 10 years.
eROSITA’s X-Ray Frontier
Already captured a population of 30+ X-ray TDEs, and its future scans should greatly improve statistics and modeling.
Gravitational Waves from Stars Dying
Future missions like LISA may detect gravitational-wave signals when stars are shredded—a chance to pioneer multi-messenger TDE astronomy.
NASA Confirms Rare Phenomenon as Three Black Holes: How We Track a TDE
1. All-Sky Monitoring
ZTF and Gaia watch for sudden brightness in galaxy centers.
2. Swift & NEOWISE Follow-Up
Once flagged, these telescopes gather X-ray, UV, optical, and IR data.
3. Light Curve Construction
Brightness trends—rise over ~100 days, fade over ~150—give TDE identity.
4. Spectral & Debris Modeling
Simulate black hole mass, spin, debris streams, and disk formation to match observations.
5. Sample & Forecast
Build TDE catalogs, test event rates, and prepare models for surveys like LSST and eROSITA.

FAQs
Q1: How often do these events occur?
About 1 per 100,000 galaxy-years—but detection is growing, with up to ~10 per year now. LSST may detect 1,000 annually.
Q2: Are these black holes supermassive?
Yes—millions to billions times the Sun’s mass, located in galaxy cores. .
Q3: How can we confirm it’s not a supernova?
TDEs show unique rise/fade curves, multi-wavelength signatures, and nuclear position. .
Q4: What is spaghettification?
It describes how a star gets stretched into long strands by intense tidal forces before it’s destroyed.
Q5: Can future gravitational-wave observatories detect these?
Yes—models predict LISA and successors could pick up signals from TDEs as early as the next decade.
