Things in the Universe that make you go Hmmmm!

Astronomers spot a new object. It appears to be a star as big as our solar system emitting 100 billion times more energy than any known star can physically produce?

Is this a "black hole star" MIT astronomers are asking .... Scientists indicate the most likely explanation for this strange new red dot is that it is a mashup of a black hole and a star. https://phys.org/news/2026-08-black-hole-star-astronomers-brand.html

What is new in the Universe, is actually very old!

The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found.

Two of these galaxy cores EUCL J172902.75+641018.1 and EUCL J125308.55+705432.3 are powered by gargantuan black holes, and are the earliest quasars yet observed in cosmic history.

Both lie just over 13 billion light-years away, and emerged during the Universe’s first 670 million years – just 5% of its current age. https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_discovers_the_most_ancient_quasar_in_the_Universe #EU #Euclid #SpaceTelescope #Space #Universe #Astronomy #Quasars #BlackHoles #Galaxy #CosmicHistory

“… Roman is set to launch on August 30, 2026, and will help us gain a wider view of the universe and collect data faster than its predecessors, such as the Hubble Space Telescope. The telescope will do so thanks to the incredible equipment and instruments built into it.
These instruments include the primary mirror, which was gifted to NASA by a U.S. intelligence agency, the Wide Field Instrument, and an advanced coronograph. Altogether, these instruments could help us map out more of the universe than we ever imagined.
“It is an incredible feat of precision engineering. It's quite possibly the most complex scientific instrument that NASA has ever built,” Dominic Benford, …program scientist for the Nancy Grace Roman Space Telescope…”

“Named after NASA’s first chief astronomer, the ‘mother of the Hubble Space Telescope,’ the Nancy Grace Roman Space Telescope will have a field of view at least 100 times larger than Hubble's, potentially measuring light from a billion galaxies in its lifetime. This observatory will also be able to block starlight to directly see exoplanets and planet-forming disks, complete a statistical census of planetary systems in our galaxy, and settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics…”

The Roman Space Telescope is engineered to investigate the biggest mysteries in astrophysics:
• Dark Energy & Dark Matter: By surveying billions of galaxies and mapping their distribution, Roman will explore why the universe's expansion is accelerating and trace cosmic history.
• Exoplanets: It will utilize gravitational microlensing to complete a statistical census of planetary systems in our galaxy, aiming to find thousands of exoplanets, including elusive rogue planets.
• Infrared Astrophysics: The telescope's deep, crisp infrared vision will help astronomers measure light from up to a billion galaxies over its lifetime.

JWST is most in-demand telescope ever - leaving many astronomers in the cold

Reviewers will likely approve only one in every nine research proposals submitted in latest application cycle. #JWSTCycle3
