Radio Signal from Early Universe May Reveal the Masses of the First Stars
A newly modelled 21-centimetre radio signal from hydrogen atoms just 100 million years after the Big Bang may reveal the mass of the universe’s first stars. Using REACH and the upcoming SKA telescopes, researchers aim to uncover how early starlight shaped cosmic evolution during the Cosmic Dawn, when the universe transitioned from darkness to lig...

Strange Planet Confirmed in Binary Star System Nu Octantis
Astronomers have confirmed the existence of a massive planet in the Nu Octantis binary star system, first suspected in 2004. Using advanced tools like the HARPS spectrograph, researchers found that the planet orbits in the opposite direction of one of the stars—a retrograde motion that keeps the system stable. The discovery of a white dwarf in th...

Bizzare 'Failed Star' Planet Orbiting Double Star System in Milky Way Discovered by Researchers
Astronomers have discovered an exoplanet 90 degrees tilted around a special pair of eclipsing brown dwarfs. This uncommon "polar planet" challenges accepted wisdom on planet creation by presenting new insights on the dynamics of binary stars and the range of Milky Way planetary orbits.

T Corona Borealis May Erupt Soon: Rare Nova Could Be Visible to Naked Eye
T Corona Borealis, a binary star system in the Northern Crown constellation, is showing signs of an imminent nova eruption. The white dwarf star, which pulls material from its red giant companion, last erupted in 1946. Astronomers have detected patterns similar to previous eruptions, leading to predictions of a possible outburst within the next two...

Two New Exoplanets Found Orbiting a Star in Draco Constellation
Astronomers have identified two exoplanets, TOI-1453 b and TOI-1453 c, orbiting a star 250 light-years away in Draco. The planets, a super-Earth and a sub-Neptune, were detected using NASA’s TESS satellite and the HARPS-N spectrograph. TOI-1453 b is a rocky planet orbiting close to its star, while TOI-1453 c is twice Earth’s size and may have a...

James Webb Space Telescope Captures Hourglass Nebula LBN 483 in Stunning Detail
The James Webb Space Telescope has captured unprecedented details of LBN 483, a nebula located 650 light-years away. The striking hourglass-shaped structure results from outflows driven by a forming binary star system. JWST’s infrared imaging and ALMA’s radio observations reveal how stellar winds, jets, and magnetic fields sculpt the nebula ove...

Mysterious Planetary-Mass Objects May Form in Young Star System Clashes
Recent research challenges traditional views on planetary-mass objects, suggesting they may form through violent interactions between young star systems rather than standard planetary or stellar processes. Simulations indicate these clashes create dense gas filaments that evolve into free-floating objects, often in binary pairs. This discovery expl...

New Polar Cataclysmic Variable Identified by Astronomers: What You Need to Know
Astronomers have detected ZTF J0112+5827, a newly identified polar cataclysmic variable. This binary system, composed of a white dwarf and a low-mass donor star, features an 80.9-minute orbital period and a strong magnetic field of 38.7 MG. It lacks an accretion disk, with emissions mainly from its accretion stream and magnetic field lines. The sys...

Vera C. Rubin Observatory to Detect Millions of Exploding Stars
The Vera C. Rubin Observatory, set to begin its 10-year Legacy Survey of Space and Time (LSST) later this year, will track millions of Type Ia supernovae to advance our understanding of dark energy. These supernovae, resulting from white dwarf stars in binary systems, will be studied in detail to provide crucial data on the universe’s acceleratin...

Hubble Telescope Observes Young Stars HOPS 150 and HOPS 153 in Orion Nebula
The Hubble Space Telescope has captured images of two young stars, HOPS 150 and HOPS 153, in the Orion Nebula, which is located about 1,300 light-years from Earth. The binary system HOPS 150 glows in bright golden red, while HOPS 153 emits a colorful jet. These stars are still in their early stages of development, feeding from their surrounding dus...

Supermassive Black Hole Flashed Twice in a Rare Event, Scientists Explain the Reason
In a galaxy 408 million light-years away, the black hole ASASSN-22ci consumed a star from a binary system, producing a rare double-flash tidal disruption event (TDE). First observed in February 2022, a second flare occurred 720 days later, possibly caused by Hills capture. Researchers anticipate a third flare in early 2026, offering unprecedented i...

White Dwarf’s Unexplainable Rapid Spin Finally Decoded by Scientists
The white dwarf star RX J0648.0–4418, 1,700 light-years away, spins at a rapid pace of 13 seconds per rotation. Part of a binary system with a helium-burning hot subdwarf star, it continues to shrink while accreting material. This rare and short-lived system provides a unique view into stellar evolution. Approaching the Chandrasekhar limit, RX J0...

Researchers Unveil New Theory on the Formation of Jupiter-Mass Binary Objects
A team of researchers has proposed a new theory explaining the formation of Jupiter-mass binary objects (JuMBOs), identified in 2023 in the Orion Nebula. The theory involves photo erosion, where radiation from massive stars strips away mass from stellar cores, shaping JuMBOs into objects with masses comparable to Jupiter. This theory sheds light on...

Binary Star System D9 Found Orbiting Sagittarius A* Near Milky Way’s Core
Astronomers have detected a young binary star system, D9, orbiting Sagittarius A*, the supermassive black hole at the Milky Way's centre. This challenges previous assumptions about star survival near intense gravitational forces. The discovery was made using the European Southern Observatory's Very Large Telescope. Future research with advanced tel...

JWST Discovers Jupiter-Mass Binary Objects in Orion Nebula, Offering New Clues
The James Webb Space Telescope has identified dozens of Jupiter-mass binary objects (JuMBOs) in the Orion Nebula. These enigmatic rogue gas giant pairs orbit each other at distances of 25 to 400 AU. Researchers propose they could be failed stars formed under extreme radiation conditions, ejected planetary systems, or a mix of both. Simulations repl...
