An international team used the XMM-Newton and NuSTAR space telescopes to study a hyper-luminous quasar, capturing the most powerful ultra-fast outflow ever observed.
XMM-Newton and NuSTAR captured record-level emissions from a hyper-luminous quasar.
Gas is expelled at ultra-fast speeds from the vicinity of the supermassive black hole.
Galactic winds of this magnitude can suppress star formation across the host galaxy.
The red planet's close approach to one of the sky's most recognizable star clusters can be seen before dawn this week. The event won't repeat for another eight years.
Mars is approaching the Pleiades in a naked-eye event visible before dawn this week.
The conjunction will not recur for another eight years.
Best viewing time is roughly one hour before sunrise, away from city lights.
The tenth known member of the genus Hemiscyllium has been found in shallow coastal waters of southeastern Papua New Guinea, distinguished by its ability to walk along the seafloor on its fins.
A new walking shark species was discovered in shallow waters off Papua New Guinea.
It is the tenth known member of the genus Hemiscyllium, which moves along the seafloor on its fins.
The find highlights the rich, underexplored marine biodiversity of the Indo-Pacific region.
A team of researchers has shown that the electrical resistance of a pure metal cannot exceed a fundamental physical ceiling — a finding with broad implications for condensed matter physics.
Researchers established that resistivity in a pure metal has a fundamental physical upper bound.
The limit stems from the quantum properties of electrons, not from the metal's chemical composition.
The finding reinforces condensed matter theory and may shape the design of future advanced materials.
A pioneering clinical study is attempting to "reprogram" retinal cells damaged by glaucoma — a potentially groundbreaking approach that also raises serious safety and ethical questions.
The world's first cellular reprogramming therapy for glaucoma has entered human clinical trials.
The technique uses viral vectors to deliver genes that "rejuvenate" damaged retinal cells.
Experts' main concern: the potential long-term risk of tumour formation from reprogrammed cells.
