Astronomers probe the nature of a massive young stellar object
Astronomers from Argentina and Spain have performed near-infrared observations of a massive young stellar object known as MYSO G29.862−0.0044. The observational campaign sheds more light on the nature of this object and its unique morphology. The new findings are presented in a paper published August 13 on the arXiv preprint server.
Massive young stellar objects (MYSOs) are stars in the very early stage of formation and the progenitors of massive main-sequence stars. However, due to their short formation timescale (about 10,000–100,000 years) and the severe extinction by the surrounding gas and dust, observations of MYSOs remain challenging.
Located some 20,200 light years away, MYSO G29.862−0.0044 (YSO-G29 for short), is a massive young stellar object associated with the star-forming region G29.96–0.02. The object is likely embedded within a dense molecular core.
Accidental double zoom reveals millimeter waves around supermassive black hole
An international team of astronomers led by Matus Rybak (Leiden University, Netherlands) has proven, thanks to accidental double zoom, that millimeter radiation is generated close to the core of a supermassive black hole. Their findings have been accepted for publication in the journal Astronomy & Astrophysics and are available on the arXiv preprint server.
Singularities are Inevitable, Physicist Claims

According to Einstein’s theories, the universe started with a Big Bang singularity and is slowly expanding until it disperses into nothingness. But physicists have also come up with theories claiming that the Big Bang was non-singular and can repeat, restarting the cycle over again. These are called “cyclic models,” and they’ve re-emerged into the spotlight now that there’s mounting evidence that dark energy is weakening over time. However, a physicist from UC Berkeley recently published a paper which he claims “categorically rules out” cyclic models. Let’s take a look.

Theoretical study reveals failure of key quark-gluon plasma probe in low-energy region
According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense “soup” composed of freely moving quarks and gluons. This state of matter is known as quark-gluon plasma (QGP). Finding definitive evidence for the existence of QGP is crucial for understanding cosmic evolution.
A laser-propelled mini spacecraft could travel to a nearby black hole, astrophysicist says
“I think it’s reasonable to expect we could find a nearby one within the next decade,” Bambi said in the statement.
Today, building the necessary laser array would cost around $1.1 trillion, far beyond the reach of current science budgets. But if trends in technology continue, Bambi estimates that cost could fall to around one billion euros within 30 years, putting it on par with current flagship space missions.
“We don’t have the technology now,” Bambi said in the statement. “But in 20 or 30 years, we might.”
Terra Quantum Brings Quantum Gravity to Quantum Computing: Advance Reduces Errors Without Added Complexity
Terra Quantum has published a groundbreaking advance in quantum error correction that redefines how we scale quantum computing. In the peer-reviewed paper “QMM-Enhanced Error Correction: Demonstrating Reversible Imprinting and Retrieval for Robust Quantum Computation”, Terra Quantum scientists present QMM-Enhanced Error Correction, a hardware-validated, measurement-free method for suppressing quantum errors, based on principles derived initially from quantum gravity.
At the heart of this innovation is the Quantum Memory Matrix (QMM), a cosmology-inspired concept that models space-time as a lattice of finite-dimensional memory cells. Terra Quantum has now translated this deep theoretical idea into a functional quantum circuit. Validated on IBM’s superconducting processors, the QMM layer functions as a lightweight, unitary “booster” that enhances fidelity without mid-circuit measurements or added two-qubit gates, offering a powerful alternative to traditional surface codes.
“We have taken a concept rooted in quantum gravity and made it plug-and-play for today’s quantum processors,” said Florian Neukart, Chief Product Officer at Terra Quantum. “QMM-enhanced error correction works out of the box on existing hardware, requires no architectural changes, and delivers measurable gains. For industries building quantum solutions now, not in 10 years. This is a game-changer.
