First Photos Of Humpback Whale Sex Are Of Two Males‚ NASA Hit An Asteroid So Hard It Changed Shape‚ And Much More This Week
This week a megalith discovered on a mountain in Peru is older than Egypt's pyramids‚ a tiny 12-millimeter-long fish makes a sound comparable to a human hearing a jet plane take off‚ and the mighty blue whale reclaims its spot as the Earth’s heaviest animal to ever live. Finally‚ we discover the bizarre behind-the-scenes story of the first-ever detection of gravitational waves.Subscribe to the IFLScience newsletter for all the biggest science news delivered straight to your inbox every Wednesday and Saturday. First-Ever Photos Of Humpback Whale Sex Involve Two MalesFor the first time‚ photographers have recorded two humpback whales copulating. When they showed their footage to a marine mammal expert‚ she confirmed both participants were males‚ confirming once again that same-sex sexual behavior is widespread among animals. There are‚ however‚ questions about whether in this case‚ both whales were happy about the situation.

The DART mission was sent to smash into asteroid Dimorphos‚ the small moon of asteroid Didymos. It was the first time humanity moved a celestial body. DART stands for Double Asteroid Redirection Test‚ and as tests go it did very well. Maybe too well. Dimorphos might have experienced global deformation from the event.

It argues that the recent claim the ~39-million-year-old Perucetus colossus – an ancient whale – was heavier than the blue whale is false‚ putting ol’ Balaenoptera musculus back on top.

The first thing you’d do is probably check everything multiple times – is this correct; is it really happening? And if you were in a big international collaboration‚ you might even want to ask around to check if this is a prank or a test. Or maybe‚ you might consider something more sinister: someone has created a fake. Read the full story hereMore content:Have you seen our free e-magazine‚ CURIOUS? Issue 20 March 2024 is out now.
