Europa’s ice shell secrets unlocked by ground radar study

Jupiter’s moon Europa has become high-value real estate for astrobiologists and the search for life beyond Earth. This is because the small moon, which is slightly smaller than Earth’s moon, boasts a massive subsurface ocean of liquid water that scientists estimate contains about double the amount of water in all Earth’s oceans combined. As seen […]

Ultra-faint galaxy discovered near Andromeda may be 12.5 billion years old

A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way’s large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, is one of the faintest satellite galaxies discovered around Andromeda to date.

The solar gravitational lens could map white dwarfs and black holes

It feels like every few months we get to report on another academic paper singing the praises of the Solar Gravitational Lens (SGL). Partly, this is due to Dr. Slava Turyshev’s astounding productivity in pumping out academic articles, but partly because such a groundbreaking mission has lots of positive aspects—as well as challenges that need […]

Reanalysis suggests ‘Phoebe’ is a variable star, not a primordial black hole

A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed “Phoebe” was simply doing something ordinary that many stars do: changing its brightness naturally over time. The new findings have been […]

Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy

Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at the center of a visible galaxy. The paper outlining this research was published in The Astrophysical Journal Letters on […]
