What seems to be a double lobe nuclear explosion is actually the result of a rare astronomical outburst known as Supernova imposter. A “small” nuclear explosion occurred in the massive star ETA Carinae almost 200 years ago, but the star still lives inside, with the two expanding lobes that are shown here as a result of the sequelae of that burst.

There is an old saying that “what you see is what you get.” However, when it comes to the universe, there are often more in complete history.
The incredible places abound throughout the universe.
This region of densely populated space focuses on the Galaxy SDSS J1004+4112 cluster, and shows several objects that appear multiplied due to the gravitational lens. Once called “Five Star” lens, star -shaped appearances that are seen near the center of the cluster are actually the same with images five times in the same field of vision: a deceptive trick of light and gravity.

But these ten examples are very different from what their appearances indicate.
Galaxy NGC 105, face face and with many spectacular characteristics, seems to be merged and superimposed with a smaller galaxy that is shown to its upper left: PGC 212515. However, this appearance is misleading; These galaxies are not related and are not even in the same neighborhood as the others. (Credit: Este/Hubble and Nasa, D. Jones, A.

The “Fund” galaxy found very close to NGC 105, PGC 212515, does not interact with its largest neighbor. In fact, these are not neighboring galaxies at all, but are separated by more than 100 million light years; They are simply along the same line of vision. The lack of distortion of tides and star currents is a revealing sign of this cosmic coincidence. (Credit: Este/Hubble and Nasa, D. Jones, A. Ries et al.; Recognition: R. Colombari)
The globular groups are round and symmetrical collections of stars filled mainly with older stars: formed in explosions many billions of years ago. This object, although it looks like a visually a globular group, is about ~ 200,000 light years away and consists exclusively of young stars; Instead, it is a cluster of open stars, but that has not yet begun to dissociate.
