When one black hole isn't enough! Most galaxies just have one. But this one has three.
The likely reason is that galaxy J1502+1115 is the product of the recent coalescence of three smaller galaxies. The two closest black holes are shown above resolved in radio waves by large coordinated array of antennas spread out over Europe, Asia, and Africa. These two supermassive black holes imaged are separated by about 500 light years and each has a likely mass about 100 million times the mass of our Sun. Currently, J1502+1115, at a redshift of 0.39, is one of only a few triple black hole system known and is being studied to learn more about galaxy and supermassive black hole interaction rates during the middle ages of our universe. Gravitational radiation emitted by such massive black hole systems may be detectable by future observatories.

The surprising results come from a new GLAAD survey.
- The survey found that 18- to 34-year-old non-LGBTQ Americans reported feeling less comfortable around LGBTQ people in a variety of hypothetical situations.
- The attitudes of older non-LGBTQ Americans have remained basically constant over the past few years.
- Overall, about 80 percent of Americans support equal rights for LGBTQ people.
Controversial map names CEOs of 100 companies producing 71 percent of the world's greenhouse gas emissions.
- Just 100 companies produce 71 percent of the world's greenhouse gases.
- This map lists their names and locations, and their CEOs.
- The climate crisis may be too complex for these 100 people to solve, but naming and shaming them is a good start.
The more we learn about the microbiome, the more the pieces are fitting together.
- A new study from the University of Central Florida makes the case for the emerging connection of autism and the human microbiome.
- High levels of Propionic Acid (PPA), used in processed foods to extend shelf life, reduces neuronal development in fetal brains.
- While more research is needed, this is another step in fully understanding the consequences of poor nutrition.
