Astronomers uncover white dwarf system emitting bright radio pulses with strange rhythm
Researchers identify a mystifying Long-Period Transient with 100% polarized radio emission, suggesting new type of cosmic radio source. A team of astronomers at ASTRON, the Netherlands Institute for Radio Astronomy, has discovered a mysterious new cosmic radio source that challenges current theories about how dead stars can produce such powerful emissions. Using the LOFAR (Low Frequency Array) radio telescope, the team picked up the unusual signal as part of a study led by astronomer Sanne Bloot. This research was published today in the scientific journal Astronomy & Astrophysics.
Exoplanet Sparks Stellar Fireworks
Astronomers have witnessed a planet causing storms to erupt on its parent star, a discovery that could reshape our understanding of how planets and stars interact and evolve together. These findings are published today in the scientific journal Nature.
New ‘mini halo’ discovery deepens our understanding of how the early Universe was formed
Astronomers have uncovered a vast cloud of energetic particles – a ‘mini halo’ – surrounding one of the most distant galaxy clusters ever observed, using the LOFAR radio telescope, marking a major step forward in understanding the hidden forces that shape the cosmos.
An Earth-sized radio observatory just got better: South Africa’s MeerKAT telescope joins forces with the European VLBI Network of telescopes
South Africa’s MeerKAT radio telescope has successfully conducted very long baseline interferometry (VLBI) observations with telescopes of the European VLBI Network (EVN)—currently the world’s most sensitive VLBI network. Their synergy sets a new standard for global collaboration and significantly enhances both resolution and sensitivity, opening new avenues for scientific exploration.
