Macquarie astronomers confirm massive planet TOI-2109b is spiralling towards its star, facing destruction via tidal forces, stellar consumption, or atmospheric stripping.

New Haven, Conn. — Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the “Infinity” galaxy — two recently-collided galaxies that, together, look like the symbol for infinity.

And at the center of “Infinity,” embedded in a cloud of gas, they say, is a supermassive black hole.

The findings are described in a new study to be published in The Astrophysical Journal Letters.

July 14th, 2025 – The Lunar Policy Platform (LPP), the Committee on Space Research (COSPAR), and the International Astronomical Union (IAU) have signed a 3 years Memorandum of Understanding (MoU) to enable and facilitate cooperation and collaboration between them supporting peaceful, safe, and sustainable lunar activities. This strategic partnership marks a significant milestone in fostering global multi stakeholder discussions for a balanced and participatory approach to lunar activities.

Can you imagine a life-saving molecule whose “twin” is a deadly poison? As surprising as it may seem, this chemical reality is known as “chirality”. Like a right hand and a left hand, two molecules can have the same composition, but a different shape and arrangement in space. And this difference can change everything. Understanding and controlling this phenomenon is crucial to drug design. A team from the University of Geneva (UNIGE), in collaboration with the University of Pisa, has developed a new family of remarkably stable chiral molecules. This work opens up new prospects for the design of geometry-controlled drugs. It is published in the Journal of the American Chemical Society.
