A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. https://t.co/NxeOUPu60R

Hubble spotted an unusual star 128 light-years away. With its unique ultraviolet capabilities, Hubble determined this star is a rare ultramassive white dwarf, made up of merged stars: https://t.co/2Hp1LBjUBC Find out more about this star's intriguing atmosphere in this video ⬇️

Seth Klarman avoids the spotlight—but his funding helps shape the Left’s policy machine.

An international team of astronomers have discovered a remarkably clumpy rotating #galaxy that existed just 900 million years after the Big Bang, shedding new light on how galaxies grew and evolved in the early Universe: https://t.co/3CKloscEhY @DurhamPhysics @NatureAstronomy

The Thirty Meter Telescope, long slated for construction in Hawaii, might be getting a new home https://t.co/9PAhmuMoNV

The Milky Way is moving through the Universe and its path is influenced by the combined gravitational pulls of nearby galaxies, such as Andromeda, the Triangulum galaxy and the Large Magellanic Cloud. @NatureAstronomy @NaturePortfolio

The #RubinFirstLook images are out...

Our June(teenth) issue is now here to read: https://t.co/YE9Q1fFjgc The cover image depicts a ticking time bomb... a supernova progenitor on our doorstep! But don't worry, we still have a good 20 billion years until it goes bang.

Gessey-Jones et al. show that future radio telescopes will be able to reveal the mass distribution of the first stars in the Universe by detecting their impact on a faint radio signal of hydrogen atoms from Cosmic Dawn. https://t.co/qRgvCGCE34 @cambridge_astro

The precessing jet in M87, exhibiting an unexpectedly broader width in the inner region, is found to be linked to a compact, tilted accretion disk, providing new insights into the jet-disk-BH configuration and formation. Cui & Lin:

Honestly they could have saved some space and just put “The entire Fairfax Uniparty vs. Libertarian Dave Crance” But still a great read - thanks @CardinalNewsVA for constantly giving all candidates, even third party a voice!

The Fermi-LAT collaboration reports a significant γ-ray detection (5.2σ) from the coronae of radio-quiet AGNs, revealing compact (∼10 gravitational radii) and extended (∼2.7×10⁶ gravitational radii) coronal regions, challenging existing models.

In a new study in @NatureAstronomy, scientists from the Jackson School took a close at Mars' thick clay terrains. They found that these areas could have provided the right mix of water, minerals and a calm environment for life to develop. Read more: https://t.co/TJ5O72922v

The Martian terrain has influenced its early surface evolution, allowing regions of stable chemical weathering to develop and permanently trap water and minerals, weakening Mars’ climate feedback and limiting long-term hydrological activity. Moore et al.:

Using a large cosmological sample of fast radio bursts, Connor et al. have measured the Universe’s missing baryons, finding that most reside in the diffuse intergalactic medium, not galaxies — confirming strong astrophysical feedback seen in simulations.

Simulations of long-term atmospheric evolution show that rocky planets with Earth-like masses in the classical Habitable Zone of Sun-like stars can retain thick He-dominated primordial atmospheres. Lammer, Scherf et al.:

A paper in @NatureAstronomy presents an optic system that produces high-resolution observations of fine structures in the Sun’s corona by lifting the veil of atmospheric blur over a fast-moving, twisted plasma stream as it becomes unstable. https://t.co/77ziSkfwKi

Multi-instrumental data analysis reveals a giant exoplanet in orbit around the 0.2 M_sol star TOI-6894. This system poses strong challenges to planet formation theories and is an excellent target for atmospheric characterisation. Bryant et al.:

A 10 M⨁ planet is detected in the habitable zone (HZ) of the solar-type star Kepler-725 using the transit timing variations technique. This study proposes a complementary pathway to probe low-mass exoplanets in the HZs of Sun-like stars. Sun et al.:

The likelihood of a collision between the Milky Way and its neighbouring galaxy Andromeda may be smaller than previously thought, according to a new simulation described in @NatureAstronomy. https://t.co/Vvz7lImmw4

. @Hubble_space and @ESAGaia join forces to revisit the fate of our galaxy. Doubt is cast on the long-held prediction that the Milky Way galaxy will collide with the Andromeda galaxy in about 4.5 billion years. Read more 👉 https://t.co/yjYiwDZExA
