How to catch a comet that hasn’t been discovered yet

There’s been a lot of speculation recently about interstellar visitor 3I/ATLAS—much of which is probably caused by low-quality data given that we have to observe it from either Earth, or in some cases, Mars. In either case, it’s much further away than what would be the ideal. But that might not be the case for a future interstellar object.

Hubble seeks clusters in ‘Lost Galaxy’

This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely faint, giving it the nickname “Lost Galaxy.”

Astronomers warn satellite growth may contaminate nearly all space telescope data

Light from the half a million satellites that humanity is planning to launch into Earth’s orbit in the coming years could contaminate almost all the images taken by space telescopes, NASA astronomers warned Wednesday.

These two galaxies are tying the knot and producing stars

Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient progenitors of galaxies like ours were small galaxies similar to modern-day dwarf galaxies like the Large and Small Magellanic Clouds. Research shows that both dwarf galaxies and ancient galaxies are less massive, have lower metallicity, and have lots of star-forming gas but relatively few stars. Astronomers try to understand ancient galaxies and how they grew to become so massive by studying dwarf galaxies that are interacting with each other and beginning to merge.

Simulations reveal how black holes generate intense light from infalling matter

Surprisingly, some of the universe’s brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a team of computational astrophysicists has developed the most comprehensive simulations ever made of how black holes create these dazzling light shows.

Pinning down spinless glueballs: New look at hidden structure inside subatomic particles

SUNY Poly Professor of Physics Dr. Amir Fariborz recently published a paper in Physical Review D titled “Spinless glueballs in generalized linear sigma model.” The work takes on a central challenge in modern physics: understanding how the strongest force in nature shapes the inner structure of matter, and how it may produce an unusual form of matter made entirely from the carriers of that force.

Tightening the net around the elusive sterile neutrino

Neutrinos, though nearly invisible, are among the most numerous matter particles in the universe. The Standard Model recognizes three types, but the discovery of neutrino oscillations revealed they have mass and can change identity while propagating.

Long-standing puzzle in electron scattering deepens with new measurement

Why does lead behave so differently from every other atomic nucleus when struck by electrons? A team of physicists at Johannes Gutenberg University Mainz (JGU) has taken an important step toward answering this question, only to find that the mystery is even deeper than previously thought. The findings were published in the journal Physical Review Letters.
